Under the project Advanced European Infrastructures for Detectors at Accelerators (AIDA), Institute of Nuclear Research (INR) and University of Geneva designed the Totally Active Scintillator Detector (TASD). The TASD detector consists of 50 modules of plastic scintillators. Each module is instrumented with one X and one Y plane, with 84 scintillator bars per plane readout using Hamamatsu MPPC’

Photek are currently in a three year development program with CERN to produce a novel square PMT for the proposed TORCH detector which is aimed at the upgrade of the LHCb experiment. The PMT will be MCP based for the inherent timing accuracy that this brings, and has three main novel features that need to be developed:
1. Long lifetime, it should be able to produce 5 C / cm$^2$ of accumulated a

The Vacuum Silicon PhotoMultiplier Tube (VSiPMT) is a new concept of photodetector based on the combination of the outstanding performances of SiPMs and the large sensitive surfaces of PMTs. Such device is made of a PMT standard envelope, with a photocathode for photon-electron conversion and an electrostatic focusing system that accelerates and focuses the generated photoelectrons towards a smal

Hyper-Kamiokande is a proposed next generation underground water Cherenkov detector capable of observing leptonic CP violation, nucleon decay, supernova neutrino and so on. Because of its large volume, 20(25) times larger than that of Super-Kamiokande for total (fiducial) mass, the total cost of photo-detectors will be expensive. Therefore cost-effective and high performance large-area photo-detec

“Horizon T” is a detector system of a new type is located at Tien Shan high-altitude Science Station of the Physical Institute of RSA at approximately 3340 meters above the sea level. It was constructed to register Extensive Air Showers (EAS) coming from a wide range of zenith angles ($0^o - 85^o$). The measurements of the time characteristics of the EAS are taken simultaneously at several reg

Time resolution improvement of the electromagnetic calorimeter PHOS (CERN/ALICE experiment) is discussed. The existing channel consists of a scintillating crystal of PbWO4 viewed by APD (avalanche photo diode) HAMAMATSU S8664-55(S8148) coupled to the low noise charge sensitive preamplifier. For improvement of the timing resolution of the detecting channel it is proposed to enter one more photodet

Two simple models of response of the Micropixel avalanche photodiode (MAPD) are proposed. The first simple discrete model describes an avalanche development and quenching in time in a single pixel. The time step is chosen as a ratio of depletion layer depth to the thermal velocity of charge carriers. Electric field and ionization coefficients for electrons and holes are recalculated before each st

We review some aspects of new and old developments in photon detection techniques. Particular emphasize is made on connections of “new” and “old” ideas in photon detection: quite often “new” ideas are well forgotten “old” ones. Comparisons are made for some “new” ideas claimed recently with “old” ideas discussed earlier, for some ideas – more than 40 years ago. Lessons le
