Abstract An essential metric for the quality of a particle-identification experiment is its statistical power to discriminate between signal and background. Pulse shape discrimination (PSD) basic method this purpose in many nuclear, high-energy rare-event search experiments where scintillation detectors are used. Conventional techniques exploit difference decay-times pulses from background events or pulse signals caused by different types radiation quanta achieve good discrimination....
Bound and resonance states of symmetric three-body exotic \(pXX\) negative atomic ions \((X=\mu^{-}, \pi^{-}, K^{-})\) as well \(ppX\) positive molecular for total angular momentum \(J=0\), are studied in details under the framework Stabilization method. The consideration lie below \(N=2\) ionization threshold corresponding \(pX\) atom. wave-function is expanded correlated multi-exponent Hylleraas type basis set explicit incorporation \(p\)-\(p\), \(\mu\)-\(\mu\), \(\pi\)-\(\pi\) or...
This paper investigates the performance of silicon microstrip detectors after heavy irradiation. Full-size prototype sensors (53 /spl times/ 64 mm/sup 2/) designed for CMS Tracker have been irradiated with protons and extensively studied in laboratory using a beam minimum ionising particles operated at low temperature as foreseen Large Hadron Collider. We present results large statistics measurements collected charge, noise, position resolution, hit finding efficiency these detectors.
We report selected results of laboratory measurements and beam tests heavily irradiated microstrip silicon detectors. The detectors were single-sided devices, produced by different manufacturers with sources, for several total ionizing doses fluences up to 4 /spl times/10/sup 14/ 1-MeV-equivalent neutrons per cm/sup 2/. Strip resistance capacitance, detector leakage currents breakdown performance measured before after irradiations. Signal-to-noise ratio efficiency studied in tests, values...
The decision-taken by the CMS experiment to build a tracker entirely based on silicon detectors has made necessary use of thicker sensors instead usual 300 /spl mu/m ones for outer part detector. We present first results performance 500 thick detectors, before and after neutron irradiation, bonded front-end electronics. Laboratory measurements show that total collected charge scales linearly with thickness when compared module measured noise is in good agreement expectations. obtained...
