5. Review of the food, water and biodiversity nexus in India

Author

Martin, J., Kanade, R., Bhadbhade, N., Joy, K.J., Thomas, B.K., Willaarts, B., Hanger-Kopp, S., Martin, J., Kanade, R., Bhadbhade, N., Joy, K.J., Thomas, B.K., Willaarts, B., and Hanger-Kopp, S.

Abstract

Nexus research can help address issues arising at the intersection of traditionally independently treated management, policy, and research areas. While an extensive body of literature and reviews have been published on the water, food and energy nexus, biodiversity is less commonly featured in food and water nexus research, particularly in India. India hosts a large proportion of the world’s biological diversity. At the same time, it is facing one of the world's highest habitat conversion rates, among others for agricultural production, as well as increasing water scarcity. Hence, the integration of biodiversity considerations into food and water nexus management and governance decisions is particularly critical in India. Here, we explore linkages at the food, water and biodiversity (FWB) nexus in India using a systematic review of peer-reviewed literature. A total of 208 nexus linkages were extracted from 55 articles and mapped using a qualitative systems mapping approach. Results show a strong interdependence between all three nexus nodes, with biodiversity exhibiting the highest number of linkages across the system (137 linkages), followed by water (131 linkages) and food (120 linkages). Our results reflect the state-of-the-art of research on biodiversity at the food-water nexus in India and highlight the importance of better understanding the linkages and tradeoffs at India's FWB nexus.

6. Integrated Conservation and Restoration Planning within a Central-European Cross-border Region

Author

Jung, M., Beier, J., Beher, J., Huchler, K., Hanger-Kopp, S., Jung, M., Beier, J., Beher, J., Huchler, K., and Hanger-Kopp, S.

Abstract

Effective conservation and restoration actions, if carefully and strategically implemented, can help to bend the curve of biodiversity loss. Yet, conflicting societal objectives and climate change can constraint such actions, and there is a need for context-specific and integrated solutions that work for biodiversity and people. We investigate conservation and restoration options within the Neusiedl lake and surrounding cross-border region, situated in Austria and Hungary. This region contains the largest central-European endorheic lake, rare ecosystems such as steppe salt ponds and provides a habitat for many species. Critically it is cultural landscape with a complex governance system and the competing demands give rise to a series of land-use and resource conflicts with biodiversity. We apply a systematic conservation planning framework customized for cross-realm and integrated conservation problems. It is integrated as it critically considers not only biodiversity, but also other perspectives towards sustainable land and water management discussed together with stakeholders in the region. Further a range of state-of-the-art remote sensing, machine learning, socio-ecological valuation techniques will be applied to identify where and how biodiversity can be preserved. Our holistic framework has the potential to provide actionable insights for stakeholders and entry points towards implementing nature-positive policies.

7. Identifying archetypes of climate vulnerability: A mixed-methods approach for heat and flood related risk in Austria

Author

Abstract

Climate change interacts with a multitude of socioeconomic characteristics (i.e. income, age, employment), determining individual risk and coping capacities. However, existing impact assessments of climate risk commonly focus on aggregate levels, leaving blind spots with respect to within-country distributional effects. Adhering to the concept of intersectionality, this study examines differential vulnerabilities and factors determining heterogeneities on a household level in the context of heat and flood related risks in Austria. We extend upon previous research by identifying differential vulnerabilities and the patterns determining heterogeneities among agents. To this end, we develop a mixed-methods approach, bringing together two ends of the spectrum: the generic representation of a single representative household and highly context specific individual risk determinants. Building on the engagement with stakeholders at different governance levels, qualitative insights from workshops and interviews are developed into narratives and storylines. These are vital for identifying key drivers of vulnerability and later integrated and combined with multivariate statistical analysis. Using the K-modes clustering algorithm, we combine geocoded socioeconomic data (e.g. age, sector and type of employment and income) with climate impact data (flood inundation level for different return periods, kysely days) on a 1kmx1km scale. Such development of archetypes aligns quantitative clusters with qualitative narratives, fostering mutual validation and a profound understanding of differential climate risk. Thus, the iterative exchange between quantitative and qualitative methods constitutes the backbone of this study. Through this approach, we identify reoccurring indicator combinations to disentangle the socioeconomic drivers of differential vulnerabilities and coping capacities in the context of flood- and heat-related climate risk. This sheds light on the within-country distribu

8. Building quantitative and qualitative archetypes of households to assess vulnerability to flood and heat-related risks in Austria

Author

Beier, J., Preinfalk, E., Hanger-Kopp, S., Beier, J., Preinfalk, E., and Hanger-Kopp, S.

Abstract

Climate change interacts with a multitude of social structures, determining individual risk and coping capacities. Existing socio-economic impact assessments of climate risk commonly focus on aggregate levels, such as GDP, leaving severe blind spots with respect to within-country distributional effects of climate change impacts. While research addressing this gap remains scarce, a profound understanding of social vulnerabilities across societal groups and the integration of these insights in impact and adaptation assessments is key for effective adaptation policy processes. Our study extends upon previous research assessing socioeconomic aggregates by shedding light on distributional effects of flood and heat-related climate risks within the Austrian society. We explore differential vulnerabilities and the patterns determining heterogeneities among agents through developing household archetypes. As this requires impact assessments to move beyond representing average regional effects, we bring together two ends of the spectrum: namely the generic representation of a single representative household and highly context specific risk determinants of individual households, by means of identifying recurring patterns.

Abstract

Climate change interacts with a multitude of socioeconomic characteristics, for example, income, age, and employment, determining individual vulnerability and coping capacities. However, existing impact assessments of climate risk commonly focus on aggregate levels, leaving blind spots with respect to within-country distributional effects. Adhering to the concept of intersectionality, this study examines differential vulnerabilities and factors determining heterogeneities on a household level in the context of heat and flood related risks in Austria. To this end, we apply a mixed-methods approach to create narratives and storylines, integrating findings from a comprehensive literature review, stakeholder workshops, semi-structured interviews, and a multivariate statistical analysis. By exploring expert’s perceptions and framings around vulnerability, we identify and highlight the complex interrelationships between drivers of social vulnerability and the distribution across society for heat and flood related risk respectively. The knowledge generated is then developed into storylines and further contextualized by insights from a K-modes clustering algorithm that is based on geocoded socioeconomic data and climate impact data on a 1kmx1km scale. Through this integrated and participatory approach, three comprehensive storylines are developed per climate risk. The storylines i) contribute to a more effective communication of social vulnerability to stakeholders working on risk management, ii) allow for a more nuanced representation of society in climate impact assessments, and iii) inform the development of just and targeted adaptation measures and pathways for the equitable distribution of adaptation benefits.

10. Justice considerations in climate research

Author

Zimm, C., Mintz-Woo, K., Brutschin, E., Hanger-Kopp, S., Hoffmann, R., Kikstra, J.S., Kuhn, M., Min, J., Muttarak, R., Pachauri, S., Patange, O., Riahi, K., Schinko, T., Zimm, C., Mintz-Woo, K., Brutschin, E., Hanger-Kopp, S., Hoffmann, R., Kikstra, J.S., Kuhn, M., Min, J., Muttarak, R., Pachauri, S., Patange, O., Riahi, K., and Schinko, T.

Abstract

Climate change and decarbonization raise complex justice questions that researchers and policymakers must address. The distributions of greenhouse gas emissions rights and mitigation efforts have dominated justice discourses within scenario research, an integrative element of the IPCC. However, the space of justice considerations is much larger. At present, there is no consistent approach to comprehensively incorporate and examine justice considerations. Here we propose a conceptual framework grounded in philosophical theory for this purpose. We apply this framework to climate mitigation scenarios literature as proof of concept, enabling a more holistic and multidimensional investigation of justice. We identify areas of future research, including new metrics of service provisioning essential for human well-being.

11. What qualitative systems mapping is and what it could be: integrating and visualizing diverse knowledge of complex problems

Abstract

Researchers in sustainability science deal with increasingly complex problems that cross administrative, geographical, disciplinary, and sectoral boundaries, and are characterized by high stakes and deep uncertainties. This in turn creates methodological challenges to frame, structure, and solve complex problems in science and practice. There is a long tradition in visualizing systems as diagrams, and concept and cognitive maps, but there is insufficient differentiation and comparison between these methods and no clear umbrella term has yet been established. Against this background, we systematically review three foundational methods from different academic disciplines—causal diagrams, concept mapping, and cognitive mapping. Comparing and contrasting them, we facilitate a coherent understanding of qualitative systems mapping (QSM) as an umbrella term. We then proceed to explore the evident intersections between these methods to showcase some of the inter- and transdisciplinary opportunities and challenges crystallizing in integrated QSM approaches. Finally, we share case study insights from the food–water–biodiversity nexus in Austria and elaborate on some of the methodological nuances to data integration in QSM. Overall, with this overview paper, we lay the groundwork for a systematic, transparent, and yet flexible development and application of QSM methods to support mixed-methods research design and clear case study documentation, as well as fostering effective inter- and transdisciplinary communication in sustainability science. Further research needs to explore these QSM applications in depth across alternative sustainability science contexts, particularly with respect to efficient and rigorous protocols for knowledge and data integration vis-a-vis complex problems and transdisciplinary research processes.

Abstract

This paper reports measurements of atmospheric neutrino and antineutrino interactions in the MINOS Far Detector, based on 2553 live-days (37.9 kton-years) of data. A total of 2072 candidate events are observed. These are separated into 905 contained-vertex muons and 466 neutrino-induced rock-muons, both produced by charged-current $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ interactions, and 701 contained-vertex showers, composed mainly of charged-current $\nu_{e}$ and $\bar{\nu}_{e}$ interactions and neutral-current interactions. The curvature of muon tracks in the magnetic field of the MINOS Far Detector is used to select separate samples of $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ events. The observed ratio of $\bar{\nu}_{\mu}$ to $\nu_{\mu}$ events is compared with the Monte Carlo simulation, giving a double ratio of $R^{data}_{\bar{\nu}/\nu}/R^{MC}_{\bar{\nu}/\nu} = 1.03 \pm 0.08 (stat.) \pm 0.08 (syst.)$. The $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ data are separated into bins of $L/E$ resolution, based on the reconstructed energy and direction of each event, and a maximum likelihood fit to the observed $L/E$ distributions is used to determine the atmospheric neutrino oscillation parameters. This fit returns 90% confidence limits of $|\Delta m^{2}| = (1.9 \pm 0.4) \times 10^{-3} eV^{2}$ and $sin^{2} 2\theta > 0.86$. The fit is extended to incorporate separate $\nu_{\mu}$ and $\bar{\nu}_{\mu}$ oscillation parameters, returning 90% confidence limits of $|\Delta m^{2}|-|\Delta \bar{m}^{2}| = 0.6^{+2.4}_{-0.8} \times 10^{-3} eV^{2}$ on the difference between the squared-mass splittings for neutrinos and antineutrinos., Comment: 22 pages, 19 figures, submitted to Phys.

Abstract

In order to meet the needs of Fermilabs planned post-collider experimental program, the total proton throughput of the 8 GeV Booster accelerator must be nearly doubled within the next two years. A system of 48 ramped corrector magnets has recently been installed in the Booster to help improve efficiency and allow for higher beam intensity without exceeding safe radiation levels. We present the preliminary results of beta function measurements made using these corrector magnets. Our goal is to use the correctors to reduce irregularities in the beta function, and ultimately to introduce localized beta bumps to reduce beam loss or direct losses towards collimators., Comment: 3 pp. Particle Accelerator, 24th Conference (PAC'11) 28 Mar - 1 Apr 2011: New York, USA

Abstract

We report an improved measurement of muon anti-neutrino disappearance over a distance of 735km using the MINOS detectors and the Fermilab Main Injector neutrino beam in a muon anti-neutrino enhanced configuration. From a total exposure of 2.95e20 protons on target, of which 42% have not been previously analyzed, we make the most precise measurement of the anti-neutrino "atmospheric" delta-m squared = 2.62 +0.31/-0.28 (stat.) +/- 0.09 (syst.) and constrain the anti-neutrino atmospheric mixing angle >0.75 (90%CL). These values are in agreement with those measured for muon neutrinos, removing the tension reported previously., Comment: 5 pages, 4 figures. In submission to Phys.Rev.Lett

Abstract

We have searched for sidereal variations in the rate of antineutrino interactions in the MINOS Near Detector. Using antineutrinos produced by the NuMI beam, we find no statistically significant sidereal modulation in the rate. When this result is placed in the context of the Standard Model Extension theory we are able to place upper limits on the coefficients defining the theory. These limits are used in combination with the results from an earlier analysis of MINOS neutrino data to further constrain the coefficients., Comment: 6 pages, 2 figures, 4 tables

Abstract

In early 2010, the Long-Baseline Neutrino Experiment (LBNE) science collaboration initiated a study to investigate the physics potential of the experiment with a broad set of different beam, near- and far-detector configurations. Nine initial topics were identified as scientific areas that motivate construction of a long-baseline neutrino experiment with a very large far detector. We summarize the scientific justification for each topic and the estimated performance for a set of far detector reference configurations. We report also on a study of optimized beam parameters and the physics capability of proposed Near Detector configurations. This document was presented to the collaboration in fall 2010 and updated with minor modifications in early 2011., Comment: Corresponding author R.J.Wilson (Bob.Wilson@colostate.edu); 113 pages, 90 figures

Abstract

We report constraints on antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% muon antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 +/- 11.7(stat) ^{+10.2}_{-8.9}(syst) events under the assumption |dm2bar|=2.32x10^-3 eV^2, snthetabar=1.0. Assuming no oscillations occur at the Near Detector baseline, a fit to the two-flavor oscillation approximation constrains |dm2bar|<3.37x10^-3 eV^2 at the 90% confidence level with snthetabar=1.0., Comment: Accepted for publication by Phys.

Abstract

We report the results of a search for $\nu_{e}$ appearance in a $\nu_{\mu}$ beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of $8.2\times10^{20}$ protons on the NuMI target at Fermilab, we find that $2\sin^2(\theta_{23})\sin^2(2\theta_{13})<0.12\ (0.20)$ at 90% confidence level for $\delta\mathord{=}0$ and the normal (inverted) neutrino mass hierarchy, with a best fit of $2\sin^2(\theta_{23})\sin^2(2\theta_{13})\,\mathord{=}\,0.041^{+0.047}_{-0.031}\ (0.079^{+0.071}_{-0.053})$. The $\theta_{13}\mathord{=}0$ hypothesis is disfavored by the MINOS data at the 89% confidence level., Comment: 5 pages, 3 figures

Abstract

Results are reported from a search for active to sterile neutrino oscillations in the MINOS long-baseline experiment, based on the observation of neutral-current neutrino interactions, from an exposure to the NuMI neutrino beam of $7.07\times10^{20}$ protons on target. A total of 802 neutral-current event candidates is observed in the Far Detector, compared to an expected number of $754\pm28\rm{(stat.)}\pm{37}\rm{(syst.)}$ for oscillations among three active flavors. The fraction $f_s$ of disappearing \numu that may transition to $\nu_s$ is found to be less than 22% at the 90% C.L., Comment: 5 pages, 3 tables, 2 figures. Published in Physical Review Letters

Abstract

This letter reports the first direct observation of muon antineutrino disappearance. The MINOS experiment has taken data with an accelerator beam optimized for muon antineutrino production, accumulating an exposure of $1.71\times 10^{20}$ protons on target. In the Far Detector, 97 charged current muon antineutrino events are observed. The no-oscillation hypothesis predicts 156 events and is excluded at $6.3\sigma$. The best fit to oscillation yields $\Delta \bar{m}^{2}=(3.36^{+0.46}_{-0.40}\textrm{(stat.)}\pm0.06\textrm{(syst.)})\times 10^{-3}\,\eV^{2}$, $\sin^{2}(2\bar{\theta})=0.86^{+0.11}_{-0.12}\textrm{(stat.)}\pm0.01\textrm{(syst.)}$. The MINOS muon neutrino and muon antineutrino measurements are consistent at the 2.0% confidence level, assuming identical underlying oscillation parameters., Comment: Six pages, four figures.

Abstract

Measurements of neutrino oscillations using the disappearance of muon neutrinos from the Fermilab NuMI neutrino beam as observed by the two MINOS detectors are reported. New analysis methods have been applied to an enlarged data sample from an exposure of $7.25 \times 10^{20}$ protons on target. A fit to neutrino oscillations yields values of $|\Delta m^2| = (2.32^{+0.12}_{-0.08})\times10^{-3}$\,eV$^2$ for the atmospheric mass splitting and $\rm \sin^2\!(2\theta) > 0.90$ (90%\,C.L.) for the mixing angle. Pure neutrino decay and quantum decoherence hypotheses are excluded at 7 and 9 standard deviations, respectively., Comment: 5 pages, 4 figures

Abstract

We searched for a sidereal modulation in the MINOS far detector neutrino rate. Such a signal would be a consequence of Lorentz and CPT violation as described by the Standard-Model Extension framework. It also would be the first detection of a perturbative effect to conventional neutrino mass oscillations. We found no evidence for this sidereal signature and the upper limits placed on the magnitudes of the Lorentz and CPT violating coefficients describing the theory are an improvement by factors of $20-510$ over the current best limits found using the MINOS near detector., Comment: 5 pages, 2 figures

Abstract

DAEdALUS, a Decay-At-rest Experiment for delta_CP studies At the Laboratory for Underground Science, provides a new approach to the search for CP violation in the neutrino sector. The design utilizes low-cost, high-power proton accelerators under development for commercial uses. These provide neutrino beams with energy up to 52 MeV from pion and muon decay-at-rest. The experiment searches for aninu_mu to antinu_e at short baselines corresponding to the atmospheric Delta m^2 region. The antinu_e will be detected, via inverse beta decay, in the 300 kton fiducial-volume Gd-doped water Cherenkov neutrino detector proposed for the Deep Underground Science and Engineering Laboratory (DUSEL). DAEdALUS opens new opportunities for DUSEL. It provides a high-statistics, low-background alternative for CP violation searches which matches the capability of the conventional long-baseline neutrino experiment, LBNE. Because of the complementary designs, when DAEdALUS antineutrino data are combined with LBNE neutrino data, the sensitivity of the CP-violation search improves beyond any present proposals, including the proposal for Project X. Also, the availability of an on-site neutrino beam opens opportunities for additional physics, both for the presently planned DUSEL detectors and for new experiments at a future 300 ft campus., Comment: Submitted to the DUSEL Directorate

Abstract

We propose a 3500 ton (3000 ton fiducial volume) SiO_2 neutrino detector with sampling calorimetry, charged particle tracking, and muon spectrometers to run in a Tevatron Fixed Target Program. Improvements to the Fermilab accelerator complex should allow substantial increases in the neutrino flux over the previous NuTeV quad triplet beamline. With 4E19 protons on target/year, a 5 year run would achieve event statistics more than 100 times higher than NuTeV. With 100 times the statistics of previous high energy neutrino experiments, the purely weak processes [\nu_{\mu} e^- \to \nu_{\mu}+ e^-] and [\nu_{\mu} e^- \to \nu_e + \mu^-] (inverse muon decay) can be measured with high accuracy for the first time. The inverse muon decay process is independent of strong interaction effects and can be used to significantly improve the flux normalization for all other processes. The high neutrino and antineutrino fluxes also make new searches for lepton flavor violation and neutral heavy leptons possible. In this document, we give a first look at the physics opportunities, detector and beam design, and calibration procedures., Comment: 65 pages, 20 figures, PDFLaTeX.

Abstract

We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction of structure functions, and the derived Parton Distribution Functions (PDFs). This experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep Inelastic Scattering (DIS) events which is over two orders of magnitude larger than past samples. We outline an innovative method for fitting the structure functions using a parameterized energy shift which yields reduced systematic uncertainties. High statistics measurements, in combination with improved systematics, will enable NuSOnG to perform discerning tests of fundamental Standard Model parameters as we search for deviations which may hint of "Beyond the Standard Model" physics., Comment: 26 pages, 13 figures

Abstract

We report the first observation of off-axis neutrino interactions in the MiniBooNE detector from the NuMI beamline at Fermilab. The MiniBooNE detector is located 745 m from the NuMI production target, at 110 mrad angle ($6.3^{\circ}$) with respect to the NuMI beam axis. Samples of charged current quasi-elastic $\nu_{\mu}$ and $\nu_e$ interactions are analyzed and found to be in agreement with expectation. This provides a direct verification of the expected pion and kaon contributions to the neutrino flux and validates the modeling of the NuMI off-axis beam., Comment: 4 pages, 5 figures, Submitted to Phys.

Abstract

This article presents the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering on Glass). This experiment uses a Tevatron-based neutrino beam to obtain over an order of magnitude higher statistics than presently available for the purely weak processes $\nu_{\mu}+e^- \to \nu_{\mu}+ e^-$ and $\nu_{\mu}+ e^- \to \nu_e + \mu^-$. A sample of Deep Inelastic Scattering events which is over two orders of magnitude larger than past samples will also be obtained. As a result, NuSOnG will be unique among present and planned experiments for its ability to probe neutrino couplings to Beyond the Standard Model physics. Many Beyond Standard Model theories physics predict a rich hierarchy of TeV-scale new states that can correct neutrino cross-sections, through modifications of $Z\nu\nu$ couplings, tree-level exchanges of new particles such as $Z^\prime$s, or through loop-level oblique corrections to gauge boson propagators. These corrections are generic in theories of extra dimensions, extended gauge symmetries, supersymmetry, and more. The sensitivity of NuSOnG to this new physics extends beyond 5 TeV mass scales. This article reviews these physics opportunities., Comment: 35 pages, 20 figures, additional citations in v2

31. Parametrization of the Driven Betatron Oscillation

Subjects
Physics - Accelerator Physics
Abstract

An AC dipole is a magnet which produces a sinusoidally oscillating dipole field and excites coherent transverse beam motion in a synchrotron. By observing this coherent motion, the optical parameters can be directly measured at the beam position monitor locations. The driven oscillation induced by an AC dipole will generate a phase space ellipse which differs from that of the free oscillation. If not properly accounted for, this difference can lead to a misinterpretation of the actual optical parameters, for instance, of 6% or more in the cases of the Tevatron, RHIC, or LHC. The effect of an AC dipole on the linear optics parameters is identical to that of a thin lens quadrupole. By introducing a new amplitude function to describe this new phase space ellipse, the motion produced by an AC dipole becomes easier to interpret. Beam position data taken under the influence of an AC dipole, with this new interpretation in mind, can lead to more precise measurements of the normal Courant-Snyder parameters. This new parameterization of the driven motion is presented and is used to interpret data taken in the FNAL Tevatron using an AC dipole., Comment: 8 pages, 8 figures, and 1 table

Abstract

A prototype Secondary-electron Emission Monitor (SEM) was installed in the 8 GeV proton transport line for the MiniBooNE experiment at Fermilab. The SEM is a segmented grid made with 5 um Ti foils, intended for use in the 120 GeV NuMI beam at Fermilab. Similar to previous workers, we found that the full collection of the secondary electron signal requires a bias voltage to draw the ejected electrons cleanly off the foils, and this effect is more pronounced at larger beam intensity. The beam centroid and width resolutions of the SEM were measured at beam widths of 3, 7, and 8 mm, and compared to calculations. Extrapolating the data from this beam test, we expect a centroid and width resolutions of 20um and 25 um, respectively, in the NuMI beam which has 1 mm spot size., Comment: submitted to Nucl. Instr.

Abstract

To date, the 120 GeV Fermilab Main Injector accelerator has accelerated a single batch of protons from the 8 GeV rapid-cycling Booster synchrotron for production of antiprotons for Run II. In the future, the Main Injector must accelerate 6 or more Booster batches simultaneously; the first will be extracted to the antiproton source, while the remaining are extracted for the NuMI/MINOS (Neutrinos at the Main Injector / Main Injector Neutrino Oscillation Search) neutrino experiment. Performing this multi-batch operation while avoiding unacceptable radioactivation of the beamlines requires a previously unnecessary synchronization between the accelerators. We describe a mechanism and present results of advancing or retarding the longitudinal progress of the Booster beam by active feedback radial manipulation of the beam during the acceleration period., Comment: Contributed to EPAC 2004; Lucerne, Switzerland

Abstract

Ion chambers used to monitor the secondary hadron and tertiary muon beam in the NuMI neutrino beamline will be exposed to background particles, including low energy neutrons produced in the beam dump. To understand these backgrounds, we have studied Helium- and Argon-filled ionization chambers exposed to intense neutron fluxes from PuBe neutron sources ($E_n=1-10$ MeV). The sources emit about 10$^8$ neutrons per second. The number of ion pairs in the chamber gas volume per incident neutron is derived. While limited in precision because of a large gamma ray background from the PuBe sources, our results are consistent with the expectation that the neutrons interact purely elastically in the chamber gas., Comment: accepted for publication in NIM A

We have developed a new focusing system for conventional neutrino beams. The ``Hadron Hose'' is a wire located in the meson decay volume, downstream of the target and focusing horns. The wire is pulsed with high current to provide a toroidal magnetic field which continuously focuses mesons. The hose increases the neutrino event rate and reduces differences between near-field and far-field neutrino spectra for oscillation experiments. We have studied this device as part of the development of the Neutrinos at the Main Injector (NuMI) project, but it might also be of use for other conventional neutrino beams., Comment: accepted for publication in Nuclear Instruments and Methods

Abstract

The Neutrinos at the Main Injector (NuMI) beam supplies an intense $\nu_{\mu}$ beam to the Main Injector Neutrino Oscillation Search (MINOS). The $\nu_{\mu}$'s are derived from a secondary $\pi^+$ beam that is allowed to decay within a 675 m decay tunnel. As part of this effort, we are developing a continuous toroidal magnetic focusing system, called the Hadronic Hose, to better steer the secondary beam. The Hose will both increase the net neutrino flux reaching the MINOS detectors and reduce systematic differences in the neutrino energy spectra at the two detectors due to solid angle acceptances., Comment: Paper submitted to the Particle Accelerator Conference (PAC2001), Chicago, Ill, June 18-22, 2001

We find the Dalitz Plot is well represented by a combination of seven quasi-two-body decay channels ($\bar{K}^{*0} \pi^0$, $K^- \rho$, $K^{*-} \pi^+$, $K^*_0(1430)^-\pi^+$, $\bar{K}^*_0(1430)^0 \pi^0$, $K^- \rho^+(1700)$, and $K^*(1680)^- \pi^+$), plus a small non-resonant component. Using the amplitudes and phases from this analysis, we calculate an integrated CP asymmetry of $-0.031 \pm 0.086$., Comment: 32 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, Version to appear in Phys.

We report on results using both plane and "sawtooth" shaped radiators. Specifically, we discuss the number of photoelectrons observed per ring and the angular resolution.

Abstract

We are constructing a Ring Imaging Cherenkov detector (RICH) for the CLEO III upgrade for precision charged hadron identification. The RICH uses plane and sawtooth LiF crystals as radiators, MWPCs as photon detectors with TEA as the photo-sensitive material, and low-noise Viking readout electronics. Results of a beam test of the first two out of total 30 sectors are presented., Comment: 7 pages, 8 figures, TeX (or Latex, etc), talk presented by J. C. Wang at DPF'99, Los Angeles, CA, 5-9 January 1999; to be published in the conference proceedings
