An 8-channel front-end ASIC has been designed in 0.35 micron CMOS technology for the upgrade of the LHCb RICH detectors at CERN. The chip allows fast single-photon counting up to 40 MHz, with a peaking time of 5 ns and a power consumption of about 1 mW per channel. Results of the characterisation of the first version of the chip are presented, including measurements in the lab with a dedicated test...
In this paper we present a study of the neutrons-induced damage in Silicon Photo-Multipliers. Twenti-six devices, produced by AdvanSiD, Hamamatsu and SensL, have been irradiated at the Geel Electron LINear Accelerator (GELINA) in Belgium on a nearly white neutron beam. The total 1 MeV equivalent integrated dose was 6.2×109neq/cm2. Photodetector performances have been measured during the whole irradiation...
The CLARO-CMOS is a prototype ASIC primarily designed for single-photon counting with multi-anode photomultipliers (Ma-PMTs), that found applications also in the read-out of silicon photomultipliers (SiPMs) and microchannel plates (MCPPMTs). The chip allows fast photon counting up to 40 MHz, with a power consumption of less than 1 mW per channel. The prototype is realised in a 0.35 micron CMOS technology...
We report radiation hardness tests performed, with a white neutron beam, at the Geel Electron LINear Accelerator in Belgium on silicon Photo-Multipliers. These are semiconductor photon detectors made of a square matrix of Geiger-Mode Avalanche photo-diodes on a silicon substrate. Several samples from different manufacturers have been irradiated integrating up to about 6.2 × 109 1-MeV-equivalent neutrons...
The superB project foresees the construction of a high intensity super-flavor factory at the Cabibbo Lab, in Tor Vergata (near Rome). The experiment, based on a high intensity asymmetric electron-positron collider, and on the related detector, is expected to reach a very high luminosity: 2 × 1036cm−2s−1, that will allow the high statistic study of rare decays and, possibly, will show evidences of...
The existing muon detectors for high-energy physics experiments are mainly made of gas chambers such as Resistive Plate Chambers, Limited Streamer Tubes or Multi Wire Proportional Chambers. With the increasing luminosity of the new accelerators and the increment in dimensions of the experiments the development of a new detection technique, which is robust, cheap and capable to sustain high particle...
We present the technology proposed for the super B muon system. The detector is based on MINOS style extruded scintillator coupled to wavelength shifting fibers. The light readout is done by means of Silicon Photomultiplier devices. We report our R&D results about charge spectra and time resolution for different readout configuration; setup optimization and experimental issues are also discussed...
