Author: S. Chiarelli, M. Panebianco, M. Prearo, R. Tarasco, G. Puzone, and M.C. Abete
Subjects: Milk, cheese, desserts, heavy metals (As, Cd, Cr, Fe, Hg, Pb), monitoring., Food processing and manufacture, TP368-456
Abstract: The contamination of food by chemical is a worldwide public health concern and is a leading cause of trade problems internationally. Contamination may occur through environmental pollution of air, water and soil, such as heavy metals (As, Cd, Cr, Fe, Hg, Pb), PCB and dioxins, or through the intentional use of various pesticides and other agrochemicals. The AA controlled, during 2007, 26 samples of milk, 2 samples of dessert and 32 samples of cheese coming from UE to the area of the City of Turin. The collected demonstrate that the environmental situation is under control and the milk, dessert and cheese fully satisfy this health requisite.

11. Stability of Quantum Eigenstates and Collapse of Superposition of States in a Fluctuating Vacuum: The Madelung Hydrodynamic Approach

Author: S. Chiarelli and P. Chiarelli
Subjects: Physics, Superposition principle, Quantum decoherence, Classical mechanics, Quantum superposition, Path integral formulation, Quantum potential, Wave function collapse, Quantum dissipation, Quantum
Abstract: The paper investigates the quantum fluctuating dynamics by using the stochastic generalization of the Madelung quantum-hydrodynamic approach. By using the discrete approach, the path integral solution is derived in order to investigate how the final stationary configuration is obtained from the initial quantum superposition of states. The model shows that the quantum eigenstates remain stationary configurations with a very small perturbation of their mass density distribution and that any eigenstate, contributing to a quantum superposition of states, can be reached in the final stationary configuration. When the non-local quantum potential acquires a finite range of interaction, the work shows that the macroscopic coarse-grained description of the theory can lead to a really classical system. The minimum uncertainty attainable in the stochastic Madelung model is shown to be compatible with maximum speed of transmission of information and interactions. The theory shows that, in the quantum deterministic limit, the uncertainty relations of quantum mechanics are obtained. The connections with the decoherence theory and the Copenhagen interpretation of quantum mechanics are also discussed.

Abstract: The GDG fabrication process developed at CNR-SPIN is a promising method for producing Bi-2212 wires without overpressure processing. In this paper, critical current measurements performed at ENEA on both short and long samples in magnetic fields up to 14 T are compared. The results show no significant difference in Je between short and long (∼1 m) samples, and suggest very good longitudinal uniformity, validating the effectiveness and scalability of the process. In addition, the suitability of Inconel 625 for reaction and test barrels is demonstrated, and the reasons for obtaining lower than expected absolute Je values are discussed.

Abstract: In the frame of the conceptual design studies for the Toroidal Field (TF) coils of DEMO, a solution based on a layer-wound magnet, rectangular-shaped Cable-in-Conduit conductors and W&R manufacturing approach, is being developed. The feasibility and performance of a large-size Nb3Sn conductor operating at about 82 kA in a 13 T field has been proven in the past. Another key technology to be demonstrated for a layer-wound TF coil, is that of a joint between two different conductor grades, to be possibly manufactured in-line during winding. The proposed joint solution would provide the minimum room occupancy, with the joint embedded within the winding pack volume. A joint between two low-field conductor grades, i.e., constituted of a small number of superconducting strands and a high number of stabilization copper wires, has been designed and manufactured. The two conductor lengths are characterized by a different number of superconducting wires and different outer dimensions. A joint sample has been assembled and instrumented, in the configuration allowing testing at the SULTAN facility of the Swiss Plasma Center. Both DC and AC performance of the joint has been characterized at the DEMO TF operating conditions. The present paper reports the main manufacturing steps for the joint and its main test results. The implications on the performance and design approach of the TF coil are also discussed, based on the outcome of such tests.

Abstract: ENEA is currently involved in the manufacture of cable-in-conduit conductors (CICCs) for the magnets of the nuclear fusion facilities ITER and JT-60SA, as well as for laboratory superconducting magnets based on CICCs, as those of the NAFASSY and of the Nijmegen-High Field Magnetic Laboratory facilities. The acceptance tests of such industrial productions include the destructive examination of both cable and conductor samples. As widely experienced, during the manufacturing processes, deformations of both copper and superconducting wires may occur due to the large compaction forces involved to which the cabled structure is subjected. In order to evaluate the maximum extent to which typical deformations can be accepted at the level of the single wire within a cable, the characterization of wires artificially deformed has been carried out in terms of mechanical, structural, and electromagnetic properties. In addition, some relevant wire sections extracted from the destructive examination samples have been also characterized. Experimental results demonstrate the negligible influence on the overall conductor performances to be expected for the typical deformations that occur during cable and conductor manufacture. © 2014 IEEE.

Abstract: Within the frame of the R&D activities carried out in Europe for the toroidal field coils of the nuclear fusion device DEMO, a fundamental milestone was considered to be the demonstration of Nb3Sn cable-in-conduit conductors (CICC) performance in the demanding range of interest for DEMO. Among the different technological solutions envisaged, the present paper deals with a wind & react CICC solution, with rectangular geometry, thick steel jacket, and distributed pressure relief channel, designed to operate at 82 kA in a magnetic field of 13 T and with a current sharing temperature ${\rm{T}}_{{\rm{cs}}}\,{\rm{> \,6.5\,K}}$ . The main manufacturing steps of the prototype conductor are described in the present paper, carried out within industrial environment, partly using the facilities and procedures available for the manufacture of ITER conductors. A sample was designed for the EDIPO facility at the Swiss Plasma Center, Switzerland, in the configuration usually adopted for the test of ITER poloidal field conductors, where the two straight conductor legs are part of the same cable length, with a continuous transition through a bottom hairpin-type joint, thus avoiding any resistive connection. The conductor has been characterized in terms of dc performance at relevant operating conditions and the absence of any performance degradation with electro-magnetic load cycles has been verified, thus, qualifying the proposed technological solution. AC losses and thermo-hydraulic tests have also been carried out, providing relevant information for further coil design.

Abstract: Within the framework of ITER-related projects, new tasks have been recently launched by EFDA CSU Garching (European Fusion Development Agreement Close Support Unit Garching), for the definition and production on industrial scale of advanced Nb3Sn strands, to be used in the manufacturing of the ITER high field CS and TF magnets. We performed an extended characterization of the advanced Nb3Sn strands coming from different European companies, in terms of strand layout (diameter, thickness of Cr coating, Cu:non-Cu ratio), critical transport current, RRR, and hysteresis losses. The results of the measurement campaign show that the upgraded strands meet the latest ITER requirements, with an overall critical transport current of at least 200 A (at 12 T, 4.2 K), equivalent to a non-Cu Jc of about 800 A/mm2, a Cu:non-Cu ratio of about 1, a strand diameter of 0.81 mm, and with non-Cu hysteresis losses limited to less than 1000 kJ/m3 on a plusmn3 T field cycle at 4.2 K

Abstract: High density MgB/sub 2/ compacts have been obtained without the need of high pressure apparatus. The key features of the sintering technique are based on the Mg liquid infiltration on powdered B preforms. Critical parameters, other than the thermal cycles, are the B powder granularity, the density of the preform and the type of the container. Centimeter-sized samples of different shapes have been obtained and the best transport critical current density, measured so far, is about 3 kA/cm/sup 2/ at T = 4.2 K and B = 9 Tesla for a sample having an overall density of 2.40 g/cm/sup 3/. Possible applications of the MgB/sub 2/ compacts are foreseeable in bulk superconducting magnets, magnetic screens and superconducting bars of variable resistance.

Abstract: A NbTi 36 strands cable-in-conduit conductor will be wound in a coil (SEx-Up Experiment) in the framework of a study of the performance of a subsize cable for the Poloidal Field Coils of ITER. The basic multifilamentary NbTi strand has been extensively characterized. The electrical characterization enabled us to get a database, essential for the future analysis of the experimental data, and to find the strand characteristic parameters for the I/sub c/(H, T) fit. We measured critical temperature vs. applied magnetic field, transport critical current vs. applied magnetic field, and magnetization vs. applied magnetic field and temperature. The last measurement gives the hysteresis losses, and implicitly the critical current values; magnetization data have been therefore correlated with direct J/sub c/ transport measurements, taking into account the self-field effect. A good match has been found, so magnetization data allowed us to enlarge the range of field and temperature toward regions in which the transport measurements are more difficult, namely low fields or high temperatures.

Abstract: Taking advantage of the large experience of the ENEA Superconducting Laboratory in the manufacture and characterization of large scale superconducting systems, a project was launched, aimed at using High Temperature Superconductor (HTS) 2G wires for the manufacture of a cable-in-conduit conductor (CICC). In particular, the main aim was the definition of a conductor design fully compatible with existing cabling technologies, to be promptly transferred to an industrial scale production. The considered layout is based on 150 HTS tapes, arranged as five layered structures of twisted tapes wound on a helically slotted core with external round jacket. All manufacturing steps (slotted core production, tape stacking and insertion into the ducts, external wrapping and jacketing) are fulfilled by using equipments and technologies available at TRATOS Cavi S.p.A. These CICCs are intended for operation using forced flow of Helium. A 2D local thermal model has been developed for the optimization of the cooling configuration. This conductor is designed to target 20 kA at 4.2 K and 15 T (or, alternatively, higher temperature, in self-field and LN2 cooling) corresponding to a Je of about 55 A/mm2. The production of a short dummy sample revealed that the exploited industrial production process is very promising for the development of HTS CICC. © 2013 IEEE.

Abstract: A new series connected 25 T hybrid magnet system is being set up by the Helmholtz Zentrum Berlin (HZB) for neutron scattering experiments. CRPP has designed and manufactured a pair of 20 kA current leads for the powering of the outer superconducting coils of the hybrid magnet system. In connection with the test of joints for JT60SA, the current leads were tested at ENEA at low voltage up to a current of 18 kA. The mass flow rates required to cool the current leads at different currents measured in the test are in line with the design calculations. For the sum of the resistances of the warm and cold end copper contacts of the HTS module values of 13 (Lead A) and 11 nΩ (Lead B) were measured. In addition, the helium flow through the heat exchanger part was stopped at 10 and 12 kA to study the behaviour of the current leads in case of a loss of flow. The time elapsed between stopping of the helium mass flow and the initiation of a quench was found to be 117 s (Lead A) and 125 s (Lead B) compared to a calculated value of 86 s. The lower value obtained by the calculation can be attributed to the lower initial temperatures in the experiment. © Published under licence by IOP Publishing Ltd.

Abstract: In the framework of the characterization and quality control of the Nb/sub 3/Sn strand for the manufacturing of the ITER (International Thermonuclear Experimental Reactor) Model Coils, the Applied Superconductivity Laboratory at ENEA (Ente per le Nuove Tecnologie Energia Ambiente) Frascati decided to increase the background field of its facility for I/sub C/ measurements from 14.5 T up to 16 T. The upgrade was obtained by an insert coil designed and manufactured by Ansaldo CRIS (Consorzio Ricerche Innovative per il Sud), Naples, Italy. The Nb/sub 3/Sn strand provided by Europa Metalli is an internal tin diffusion high critical current density 0.90 mm wire with the following characteristics: I/sub C/=160 A@4.2 K, 16.5 T; Cu/nonCu ratio 1. The solenoid (outer diameter 80 mm, inner bore 37 mm) was manufactured by winding the insulated Nb/sub 3/Sn strand onto an AISI 316L, stainless steel former and reacting it up to 650/spl deg/C. A self consistent unit has then been assembled, consisting of the insert module, mechanical structure and separate current leads. This allows easy installation of the insert inside the 14.5 T, 80 mm background magnet; removal is possible also in cold conditions without damage. The operational current (113.7 A) was achieved at the first energization with a maximum field on the windings of 16.49 T. This test has been done connecting electrically in series the background magnet and the insert, being therefore limited by the maximum allowable current (114 A) in the background magnet. Further tests with an independent current supply to the insert will be carried out to evaluate its performance limits.

Abstract: Dislocation velocities between 1100 and 1450°C in 9·4mol.%Y2O3 fully stabilized cubic ZrO2 single crystals were studied using the stress pulse-etch-pit technique. The stress and temperature dependences of the edge and screw dislocation velocities were measured at engineering stresses from 60 to 185 MPa. The activation energy for motion of the edge dislocations (5·0 ± 0·0·4 eV) is slightly lower than that for screw dislocations (5·6±0·6eV). At the lower end of the temperature range, the stress exponent m of the edge dislocation velocities is close to unity but increases modestly (to about 3·6) with increasing temperature. With reasonable choice of parameters, the data can be attributed to a Peierls potential, to jog dragging or to solute pinning.

Abstract: High performance Nb/sub 3/Sn strands for the high field ITER (International Thermonuclear Experimental Reactor) magnets have been manufactured using diffusion barriers among the multifilamentary cores and the stabilizing copper. In the conductor development programme, billets using a single Ta or a double NbV barrier have been assembled. The barrier is shown to have an influence on magnetization characteristics. The measurements on samples from the two types of strands are shown and analyzed to correlate them with the magnetic behaviour of Nb at low field. The results show that at low field hysteretic losses are greatly increased by the pure Nb of the barrier. At high field, losses of samples with Ta barrier are larger, due to their higher J/sub c/. >

Abstract: We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a W or Z boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating from Fermilab Tevatron p (p) over bar collisions at root s = 1.96 TeV, correspond to integrated luminosities of up to 9.7 fb(-1). The searches are conducted for a Higgs boson with mass in the range 100-150 GeV/c(2). We observe an excess of events in the data compared with the background predictions, which is most significant in the mass range between 120 and 135 GeV/c(2). The largest local significance is 3.3 standard deviations, corresponding to a global significance of 3.1 standard deviations. We interpret this as evidence for the presence of a new particle consistent with the standard model Higgs boson, which is produced in association with a weak vector boson and decays to a bottom-antibottom quark pair.

Abstract: The top quark is the heaviest known elementary particle, with a mass about 40 times larger than the mass of its isospin partner, the bottom quark. It decays almost 100% of the time to a W boson and a bottom quark. Using top-antitop pairs at the Tevatron proton-antiproton collider, the CDF and D0 Collaborations have measured the top quark’s mass in different final states for integrated luminosities of up to 5.8 fb(-1). This paper reports on a combination of these measurements that results in a more precise value of the mass than any individual decay channel can provide. It describes the treatment of the systematic uncertainties and their correlations. The mass value determined is 173.18 +/- 0.56 (stat) +/- 0.75 (syst) GeV or 173.18 +/- 0: 94 GeV, which has a precision of +/- 0.54%, making this the most precise determination of the top-quark mass.

Abstract: The combination of searches performed by the CDF and D0 collaborations at the Fermilab Tevatron Collider for neutral Higgs bosons produced in association with b quarks is reported. The data, corresponding to 2.6 fb(-1) of integrated luminosity at CDF and 5.2 fb(-1) at D0, have been collected in final states containing three or more b jets. Upper limits are set on the cross section multiplied by the branching ratio varying between 44 pb and 0.7 pb in the Higgs boson mass range 90 to 300 GeV, assuming production of a narrow scalar boson. Significant enhancements to the production of Higgs bosons can be found in theories beyond the standard model, for example, in supersymmetry. The results are interpreted as upper limits in the parameter space of the minimal supersymmetric standard model in a benchmark scenario favoring this decay mode.

Abstract: We report the combination of recent measurements of the helicity of the W boson from top quark decay by the CDF and D0 collaborations, based on data samples corresponding to integrated luminosities of 2.7-5.4 fb(-1) of p (p) over bar collisions collected during Run II of the Fermilab Tevatron collider. Combining measurements that simultaneously determine the fractions of W bosons with longitudinal (f(0)) and right-handed (f(+)) helicities, we find f(0) = 0.722 +/- 0.081[+/- 0.062(stat) +/- 0.052(syst)] and f(+) = -0.033 +/- 0.046[+/- 0.034(stat) +/- 0.031(syst)]. Combining measurements where one of the helicity fractions is fixed to the value expected in the standard model, we find f(0) = 0.682 +/- 0.057[+/- 0.035(stat) +/- 0.046(syst)] for fixed f(+) and f(+) = -0.015 +/- 0.035[+/- 0.018(stat) +/- 0.030(syst)] for fixed f(0). The results are consistent with standard model expectations.

29. A dislocation mechanism of crack nucleation in cubic zirconia single crystals

Author: A. S. Chiarelli, Arthur H. Heuer, and B. Ya. Farber
Subjects: Materials science, Physics and Astronomy (miscellaneous), Lüders band, Metals and Alloys, Nucleation, Plasticity, Condensed Matter Physics, Indentation hardness, Electronic, Optical and Magnetic Materials, Crystallography, Transmission electron microscopy, Indentation, General Materials Science, Cubic zirconia, Dislocation, Composite material
Abstract: The dislocation structure around elevated-temperature indentations on {111} planes of 9·4 and 21 mol.% Y2O3 fully stabilized cubic ZrO2, was investigated using selective etching and transmission electron microscopy (TEM). The temperature dependences of the microhardness and the extent of the plastic zone were measured. Different fracture modes were detected in the two materials. Cracking arising from interaction between slip bands was observed in the 21 mol.% Y2O3 material and direct evidence of the formation of Lomer-type dislocation pile-ups leading to crack nucleation was obtained by TEM. The mechanisms of dislocation plasticity and fracture during indentation of cubic zirconia are discussed.

Abstract: We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process gg -> H -> W+W- in p (p) over bar collisions at the Fermilab Tevatron Collider at root s = 1.96 TeV. With 4.8 fb(-1) of integrated luminosity analyzed at CDF and 5.4 fb(-1) at D0, the 95% confidence level upper limit on sigma(gg -> H) x B(H -> W+W-) is 1.75 pb at m(H) = 120 GeV, 0.38 pb at m(H) = 165 GeV, and 0.83 pb at m(H) = 200 GeV. Assuming the presence of a fourth sequential generation of fermions with large masses, we exclude at the 95% confidence level a standard-model-like Higgs boson with a mass between 131 and 204 GeV.

Abstract: We combine searches by the CDF and D0 Collaborations for a Higgs boson decaying to W+W-. The data correspond to an integrated total luminosity of 4.8 (CDF) and 5.4 (D0) fb(-1) of p (p) over bar collisions at root s = 1.96 TeV at the Fermilab Tevatron collider. No excess is observed above background expectation, and resulting limits on Higgs boson production exclude a standard model Higgs boson in the mass range 162-166 GeV at the 95% C.L.

Abstract: To evaluate whether histological chorioamnionitis (HCA), in the setting of preterm premature rupture of membranes (PPROM), affects infant respiratory outcome.A prospective histological study on 287 consecutive placentas was performed in preterm infants (or=32(+6) weeks gestation), categorised into four groups: according to the presence or absence of HCA, in the setting or in absence of PPROM.Neonatal intensive care unit, Department of Pediatrics, Padua University, Padua, Italy from January 2001 to December 2006.Among the 287 NICU admitted preterm infants, 68/287 (23.6%) presented with HCA, 16/68 (23.5%) with a coexisting fetal inflammatory response, and 74/287 (25.7%) with PPROM. HCA was associated with a greater frequency of vaginal delivery (P0.0001), lower gestational age (P0.0001) and lower birth weight (P0.01). HCA had no effect on fetal lung maturation, however, it was a significant risk factor for CLD (RR; 95% CI 2.08; 1.30-3.33). HCA and the fetal inflammatory response were also significant risk factors for PPROM (RR; 95% CI 2.07; 1.42-3.03 and 2.64; 1.71-4.09 respectively). Conversely, HCA in the setting of PPROM failed to reveal any RDS protection or subtype CLD risk. Multivariate analysis demonstrated significant independent effects of presence of maternal HCA (P = 0.04), gestational age (P0.0001) and interaction HCA-gestational age (P = 0.04) on CLD development, regardless of the presence of fetal HCA or fetal HCA-gestational age interaction, PPROM or PPROM-gestational age interaction.Histological chorioamnionitis is a significant PPROM and CLD risk factor, but it fails to provide any protection from RDS. HCA in the setting of PPROM also failed to reveal any RDS protection or subtype CLD risk.

Abstract: Critical currents have been measured on subsize cables, up to the 27-strand level, of the 40-kA NET-EM/LMI Nb/sub 3/Sn prototype conductor for the OH solenoid of NET (Next European Torus). Energy losses in basic strands were determined by magnetization cycles. Copper and stainless steel were used as conduit materials to produce CIC (cable-in-conduit) conductors with a 0.35 void fraction, which is lower than that of the full-size conductor. The experimental results have shown that, compared to the single-strand current, practically no degradation is observed in cables with a Cu conduit, while the cables with a stainless steel conduit have a critical current lowered by cool-down strain to 0.57 of the expected current in a 27-strand cable at zero intrinsic strain. The measurements of AC losses have indicated high hysteretic losses (effective diameter of =70 mu m). Coupling losses are expected to be negligible.

34. Endometrial cancer: asymptomatic endometrial findings. Characteristics of postmenopausal endometrial cancer

Author: M, Marchetti, C, Vasile, and S, Chiarelli
Subjects: Postmenopause, Humans, Female, Uterine Hemorrhage, Prognosis, Aged, Endometrial Neoplasms, Neoplasm Staging
Abstract: Endometrial cancer affects patients at every age, however it occurs more frequently in menopause (50) and in postmenopause (70). The most frequent symptoms are bleeding and vaginal discharge. When hematometra or pyometra is present the patient may feel pain. In some cases endometrial adenocarcinoma is asymptomatic and the diagnosis is casually made during ultrasound examination or by histological examination of a uterus surgically removed for other indications. In these cases the most frequent findings are polyps and abnormally increased thickness of the endometrial mucosa. In postmenopause polyps and abnormal endometrial thickness are usually limited to a small area and surrounded by atrophic mucosa. Higher incidence rates of endometrial cancer were correlated with polyps and an increased number of serous type tumors were identified in the65-year age group. Endometrial carcinoma may be estrogen correlated or non-estrogen associated. Patients in postmenopause are often affected by non-estrogen correlated endometrial carcinoma. According to Kurman and other authors the first type of endometrial adenocarcinoma (estrogen correlated) is characterized by low-grade malignancy. On the contrary, non-estrogen correlated neoplasia is more aggressive. In our case series including 102 women aged70 years with endometrial carcinoma we found that survival was correlated with stage and grading - early stages were the most frequent and the grade increased with stage. In fact all the patients with relapses had grade 2 or 3 adenocarcinomas. Thirty-one patients70 years (30.69%) had a non-endometrioid type of cancer.

Abstract: Publisher Summary This chapter illustrates the design and manufacturing of the insert coil and also gives a description of the test facility layout. A magnet wound with a sub-size NbTi conductor has been realized to study its characteristics in view of the realization of the full-size conductor for the ITER Poloidal Field Coils. The coil has been designed and constructed by ENEA and Ansaldo CRIS, with a conductor provided by Europa Metalli Superconductor and consisting of 36 Ni-coated strands twisted in a three stage cable, jacketed and compacted in a SS round tube. A self consistent unit has been manufactured assembling the insert module and its mechanical supporting structure, to allow easy installation inside the background magnet of the ENEA test facility where the coil will be tested under representative conditions for the ITER PF magnets. After having determined stability conditions with uniform transport current, the same rims will be repeated parametrically varying non-uniform current distribution inside the cable. The same kind of measurements will then be repeated after reversing the helium flow. This will cause the transition region to move along the conductor length, owing to the interplay between the self-field profile and the steep temperature profile along the conductor length.

Abstract: In the literature and in our experience epidermoid cysts and carcinoids of the ovary are rare benign pathologies which occur more frequently in younger women. They probably are a one-sided development of a teratoma, which arise from germ cells after the first meiotic division due to either a meiosis I or a meiosis II non dysjunction. Diagnosis is possible only with histological examination and immunohistochemistry which allow us to differentiate carcinoids from sex-cord tumors and ependymomas. Prognosis is very good because the rate of malignant transformation is 1.4%-2% and the rate of complications is 14%. Thus conservative surgical therapy associated with long-term follow-up is the treatment of choice.

Abstract: A crucial issue for a superconducting coil in order to be safely used in the magnetic system of a fusion reactor is stability against all foreseen disturbances. To simulate the fusion machine conditions, including off-normal events, e.g. plasma disruptions, the energy deposition has to be spread over a "long length" cable in conduit conductor (CICC) and a background magnetic field is needed. We have therefore designed and built an experiment consisting of an instrumented NbTi test module inserted in a pair of co-axial pulsed copper coils. A 0.6 m diameter superconducting coil provides a background magnetic field up to 3 T. Calibration of the energy inductively coupled between the pulsed coils and the module has been obtained measuring the system temperature increase just after the pulse by means of thermometers positioned along the conductor. Stability vs. operating current I/sub op/ has been examined for different helium temperatures and different background magnetic fields. The finite element code Gandalf for the stability and quenching transients analysis in forced flow cooled superconducting coils has been run to check the matching with the experimental results.

Abstract: This paper describes the results of the measurements performed in June 2011 on a NbTi cable-in-conduit conductor curved joint in the ENEA Superconductivity Laboratories (C.R. Frascati). The effectiveness of the joint design, patented by ENEA, had been already verified for the Nb3Sn EDIPO conductor; in this case, it has been applied to a NbTi cable-in-conduit conductor. The joint was manufactured and instrumented by ENEA, using part of a JT-60SA toroidal field conductor sample (namely the TFCRS) produced by Luvata Italy and successfully tested in SULTAN. For testing purposes, the NbTi 'shaking hands'-type joint was hosted in a variable temperature cryostat with a background superconducting magnet. The sample was used as the secondary coil of a transformer having the background magnet as primary coil. Measurements were preceded by preliminary code simulation studies computed in the Matlab workspace, and by 3-D finite element method analyses, to estimate the test requirements and its feasibility. The joint resistance value, found to be less than 2 nΩ has been derived both by the sample current decay time constant evaluation and by calorimetric calculations. After a short description of the joint design and fabrication, as well as of the test instrumentation and geometry, the joint resistance evaluation will be presented, together with the data analysis procedures and results. © 2012 IEEE.

Abstract: The European and the Korean contributions to the ITER Project in terms of cable-in-conduit conductors have been assigned to the Italian Consortium for Applied Superconductivity (ICAS). ICAS' charter members are: ENEA, with the role of general supervision and monitoring, CRIOTEC Impianti S.r.l., in charge of jacketing activities, and TRATOS Cavi S.p.A., with the duty of cable manufacturing. The ITER production consists of about 40 km of Nb3Sn toroidal field (TF) conductor and 22 km of NbTi poloidal field (PF) conductor, for coils 1 and 6. As part of the EU contribution to the construction of the JT-60SA Japanese Tokamak Reactor, ICAS is also in charge of producing about 28 km of NbTi TF conductor, required for the whole TF magnet system. Thanks to the high level and unique expertise available at ICAS, the consortium has been also assigned to manufacture the ITER Central Solenoid conductor samples to be tested in SULTAN for the final, positive, assessment of the updated design. In the present paper, the steps leading to the successful qualification of the main production processes will be described. What is more, the manufacturing of the first conductor unit lengths of the 'production phase,' i.e., the ones that will be wound to operate in the actual ITER TF and JT-60SA TF superconducting magnets, will be reported. The fabrication of the ITER CS conductor samples will be illustrated as well. © 2012 IEEE.

Abstract: The on-going construction of the ITER and JT-60SA tokamak reactors requires the production of a large quantity of Cable-In-Conduit Conductors (CICCs) to be employed in the superconducting magnets for plasma confinement and control. A new company, named ICAS (Italian Consortium for Applied Superconductivity), was established thanks to the large expertise in this field that has been present in Italy for nearly three decades. ICAS is a consortium among ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development) and two Italian private companies: CRIOTEC Impianti, which owns an 850m long jacketing line for CICCs, and TRATOS Cavi, which has a large experience in cable manufacturing for various applications. ICAS' current activities are aimed at supplying to Fusion for Energy the European quote of ITER TF and PF conductors and the whole JT-60SA TF conductor quantity, as well as at supplying to the Korean Domestic Agency about 19 km of ITER TF conductor. This paper offers an overview of ICAS' technical capabilities and facilities, and outlines the first outcomes from the first productions.

50. Variable-temperature characterization of NbTi strands in the low critical-current density range

Abstract: A facility for the characterization of superconducting strands at variable temperatures has been recently upgraded at ENEA. Measurement of transport properties of superconducting strands can be now carried out in the temperature range from 3.5 K to 15 K, with stability less than 10 mK, and in magnetic fields up to 12.5 T, covering a range of critical currents between a few Amperes, up to about 300 A. In this study we present the results of a measurement campaign carried out on NbTi wires, aimed also at comparing the performances of some available candidate strands, to be used in the design of the Toroidal Field Coils of the JT60-SA Tokamak, as well as in the design of the ITER high field Poloidal Field Coils, PF1 & 6. We measured strands with different diameters, and with Cu-nonCu ratios ranging between about 1.5, up to about 7. The measurements showed the critical behavior of the NbTi in the range of relatively high temperatures (T > 5.5 K) and high magnetic fields (B > 6 T), typical for large coils in fusion reactors, where Cable-in-Conduit Conductors are used and where temperature margins of at least 1K are required for a sound design. The experimental results highlighted the need for an optimization of the numerical fits normally used to predict NbTi critical current densities, starting from measurements performed at 4.2 K. Based on our results, we conclude that fit parameters for each NbTi strand should be inferred from experimental characterizations in the temperature and magnetic field range of interest for the design.
