Array of SiPMTs may be used, in place of fast conventional
photomultipliers (PMTs), for the readout of scintillator based time-of-flight systems. These new detectors are insensitive to external magnetic fields, have lower cost than traditional PMTs and present a compact design.
Comparison of the obtained timing resolutions as respect to
the baseline one (~ 50 ps) obtained with Hamamatsu...

Abstract–For Hamamatsu silicon-photomultipliers (SiPM) S10362-11-050P before and after irradiation to 200 Gy, 20 kGy, 2 MGy and 20 MGy, forward current–voltage, reverse current–voltage, capacitance/conductance–voltage, capacitance/conductance–frequency, pulse shape and pulse height measurements below and above the breakdown voltage were performed. The data were analysed using an electrical...

An irradiation test on 16 Silicon Photo Multipliers produced by Hamamatsu has been performed in Louvain-la-Neuve at the CRC-CYCLONE 110 facility.
The devices has been irradiated with neutrons in three dose steps: 5x10^8 1MeV-neutron equivalent (neq), 5x10^9 neq and 5x10^10 neq. After each irradiation step the characteristic current-voltage curves and a high statistics sample of...

Silicon photomultipliers (SiPMs) are solid state photo detectors that combine all of the features necessary for
the photon detection of a high resolution scintillating fibre tracker. Two SiPM manufacturers, Hamamatsu and KETEK have
developed customized devices for SciFi Tracker application in the context of the LHCb tracker upgrade. These custom devices
provide high photon detection...

We present the newly developed Position Sensitive Scintillating Muon SiPM -Detector (POSSUMUS). This modular designed scintillation detector is capable to determine
particle's position two-dimensional with resolution of a few mm for minimum ionizing
particles. POSSUMUS is usable for large area trigger applications with few readout
channels.
The idea of this detector is to combine...

Manufacturing plans for “next generation” microchannel plates (MCPs) and the technical advantages enabled by this evolving technology will be presented. The Large Area Picosecond Photodetector (LAPPD™) is an MCP based photodetector, capable of imaging, with high spatial and temporal resolution in a hermetic package with an active area of 400 square centimeters. A key component of LAPPD™ is a...

We developed the micro-channel-plate (MCP) PMT for the Time-of-Propagation (TOP) counter, which is a novel Cherenkov counter to be used for particle identification in the Belle II experiment. The developed MCP-PMT has excellent performance for single photon detection; a timing resolution of about 40ps (sigma, including readout jitter), a nominal gain as high as 2 x 10^6, and a position...

TORCH (Time Of internally Reflected CHerenkov radiation) is an innovative time-of-flight system designed to provide particle identification over large areas up to a momentum of 10 GeV/c. Cherenkov photons emitted within a 1 cm thick quartz radiator are propagated by internal reflection and imaged on to an array of Micro-Channel Plate photomultiplier tubes (MCPs).
Performing 3$\sigma$...

For experiments at VEPP-2000 e+e- collider with SND detector the particle identification system based on the threshold aerogel Cherenkov counters was developed. The counter design is based on ASHIPH technique (Aerogel, SHifter, PHotomultiplier). Cherenkov light emitted in aerogel is collected by a wavelength shifter and detected by a photomultiplier tube based on microchannel plates (MCP...

For the Belle II experiment at the superKEKB accelerator, we have been developing a proximity focusing ring imaging Cherenkov detector using a silica aerogel as a radiator (A-RICH). This counter is designed to be used at the forward endcap region and to have pion/kaon separation with more than 4-sigma deviations at momenta up to 4 GeV/c. 144-channel Hybrid Avalanche Photo-Detector (HAPD)...

Architectures based on MicroPattern Gas Detectors (MPGD) represent a possible answer to the quest for novel gaseous counters with single photon detection capability able to overcome all the limitations of the present generation of gaseous photon detectors. In Cherenkov imaging counters, gaseous photon detectors are still the unique option when insensitivity to magnetic field, low material...

Vacuum Silicon PhotoMultiplier Tube (VSiPMT) is an innovative photodetector based on the combination of SiPM and PMT technologies. The basic idea consists in replacing the classical dynode chain of a PhotoMultiplier Tube with a SiPM.
Such a design was proposed by our group in order to match the goal of a large photocathode sensitive area with the unrivalled photon counting performances of...

We develop superconducting tunnnel junction (STJ) to search for radiative decays of cosmic background neutrino using cosmic infrared background energy spectrum.
The requirement for performance of the detector in our experiment is to detect a single far-infrared photon.
We can detect a single far-infrared photon with Nb/Al-STJ theoretically. So far we have not succeeded in detecting it yet...
