Dr Nicolas Arnaud (LAL-Orsay)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterNew generation flavor factories like SuperB require very good charged particle identification. In SuperB, the barrel region is covered by a new detector based on the successful BaBar DIRC – the FDIRC, see separate contribution at this conference. To extend this excellent coverage down in polar angle, an additional detector has been designed for the forward region. Thin enough to fit between...Go to contribution page

Mr Nicola Casali (INFN Laboratori Nazionali del Gran Sasso)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterBolometers have proven to be good detectors to search for rare processes because of their excellent energy resolution and for their extremely low intrinsic background. The CUORE experiment, that aims at studying neutrino-less double beta decay, is building a detector made of 988 TeO$_2$ crystals, 0.750 kg each, kept at a temperature of 10 mK. In this kind of experiments, the capability of...Go to contribution page

Dr Dario Moricciani (ROMA2)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterIn order to have access to the reaction $e^+e^- \to e^+e^- \gamma\gamma$ in the energy region of the phi meson production, new detectors along the (DAFNE) beam line have to be installed in order to detect the scattered $e^+e^-$. The HET detector is used for measuring the deviation of leptons from their main orbit by determining their position and timing so to tag gg physics events and...Go to contribution page

Dr Rosaria Grasso (UNICT)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterTime resolved imaging up to the single photon sensitivity is one of the most ambitious and important goals of photonics. In the last decades the time correlation analysis has been fundamental for the study of many scientific topics. Actually it has performed only by using the information of few points in the image. The implementation of such devices based on SPADs (Single Photon Avalanche...Go to contribution page

Dr Stefan Koperny (AGH, University of Science and Technology, Faculty of Physics and Applied Computer Science)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterGas gain is one of the main parameter of proportional counter. It was measured that this value depends on type of detected radiation and for beta particle is higher by (6-8)% than for X-rays. Over some value of current flowing threw the counter (Ic-critical current) the reduction in gas gain due to space charge defined by the time of evacuation of positive ions is observed. The value of Ic...Go to contribution page

Dr Angela Papa (Paul Scherrer Institut)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterThe silicon photomultiplier (SiPM) is a recent and established evolution of the avalanche photodiode (APD). This device is particularly appropriate for use in scintillation detection because of its high sensitivity, high quantum efficiency, and insensitivity to magnetic field (up to 4 T). Excellent time and energy resolution in addition to small size and high efficiency are crucial for...Go to contribution page

Mr Stefan Gundacker (CERN)25/05/2012, 18:41P3 - PID and Photo DetectorsPosterThe time resolution of photon detection systems is important for a wide range of applications in physics and chemistry. It impacts the quality of time-resolved spectroscopy of ultrafast processes and has a direct influence on the best achievable time resolution of time-of-flight detectors in high-energy and medical physics. For the characterization of photon detectors, it is important to...Go to contribution page

This new material in fact can be easily obtained chemically by CVD (Chemical Vapour Deposition) as a layer of nanotubes growth on a wide variety of materials. When growth on a semi conductive silicon surface, CNT create a...Go to contribution page

The detectors are based on the use of THGEMs, arranged in a multilayer architecture, where the first layer is coated with a CsI film, acting as a reflective photocathode. The response of single layer THGEMs with various geometries and different conditions was extensively studied and photon detector...Go to contribution page

The NA62 experiment at the CERN SPS will measure this BR to within about 10\%.
