Abstract

The NOE Collaboration has proposed a transition radiation detector (TRD) interleaved with marble targets to tag the electron decay channel of tau leptons produced by v(tau), eventually originated by upsilon (mu) oscillations in a long base line experiment. A reduced scale TRD detector prototype has been built and exposed to an electron/pion beam at the CERN PS. Discrimination capabilities between electrons and both charged and neutral pions, representing the main source of background for our measurement, have been determined obtaining rejection factors of the order of the tenth of percent for charged pions, and of a few percent for the neutral pion, matching the experiment requirements. The capabilities of this detector to measure the energy released by particles that start showering inside the targets are shown, A momentum resolution sigma (p)/p less than or equal to 40% is found for muons in the range of 1-7 GeV/c.

Abstract

An intense R&D program has been carried out by the NOE Collaboration during the last years, to develop a massive fine grain scintillating fiber calorimeter, to be used, in combination with an appropriate target, in a Long Base Line experiment at the CERN to Gran Sasso (CNGS) neutrino beam. The performance of a 4 ton NOE calorimeter prototype exposed to a test beam at CERN PS is shown. Results on the linearity, electromagnetic and hadronic energy resolution are reported and compared with the Monte Carlo predictions.

Abstract

The NOE Collaboration has proposed a calorimeter to measure the energy of the final states of ν interaction events. The properties of long scintillator bars with wavelength-shifting fiber readout have been studied to develop a calorimeter design option. Various prototypes have been exposed to a cosmic rays stand. The total measured light yield in the middle of a 6 m -long fiber is about 15 photoelectrons. With this photon collection performance, it has been simulated that the calorimeter can achieve 17%/ E and 50%/ E resolutions for electrons and pions, respectively.

Abstract

The development of the NOE calorimeter, based on scintillating fiber technology, has undergone four years of intense R&D activity. Measurements of light attenuation and time resolution have been carried out on a variety of commercially available scintillating fibers. Both these parameters are important for the optimization of the design of the NOE calorimeter. Experimental results on the fiber attenuation length and light yield make us confident on the possibility to build a 8×8 m 2 cross-section calorimeter without noticeable loss of signal. The time resolution is resulted to be of the order of 1 ns, sufficient for up/down discrimination in the final calorimeter setup, by means of the time-of-flight method. Several tests performed to optimize the elementary cell of the calorimeter are also described.

6. Capturing the often-elusive diagnosis of idiopathic myointimal hyperplasia of mesenteric veins.

Abstract

Only 50 cases of idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) have been reported since 1991 when it was first described. This rare etiology for chronic colonic ischemia is often debilitating to the patient's quality of life, and no effective medical treatment is available. IMHMV is frequently confused with inflammatory bowel disease because the most common presenting symptoms include abdominal pain, diarrhea, and hematochezia. Surgical resection is curative; however, the diagnosis is rarely reached preoperatively. In the present report, we have described the seventh patient with a diagnosis of IMHMV before surgery and included a literature review to help clinicians recognize this condition., (© 2022 Published by Elsevier Inc. on behalf of Society for Vascular Surgery.)
