Novel Photo-Detectors and Photo-Detector Systems
Recent developments in photo-detectors and photo-detector systems are reviewed. The main emphasis is made on Silicon Photo-Multipliers (SiPM) novel and very attractive photo-detectors. Their main features are described. Properties of detectors manufactured by different producers are compared. Different applications are discussed including calorimeters, muon detection, tracking, Cherenkov light ...
متن کاملInfrared photo-induced absorption spectroscopy of porous silicon
The quantum confinement model, which assigns some of the luminescence features in porous silicon to size quantization in Si nano-crystallites, also predicts quantization of both the conduction and valence bands into sub-levels. In order to resolve this effect we have used a new experimental technique called “photo-induced infrared absorption spectroscopy”. Here, a pump, visible laser, optically...
متن کاملPhoto-processing of silicon nitride
Silicon nitride films were synthesized using the new process of photo-chemical vapour deposition (photo-CVD). Films of different compositions were prepared by mercury-sensitized photo-CVD using 2% silane and ammonia as reactant gases. Material properties of interest to device technology have been evaluated. Dependence of the properties of the films on the Si/N ratio and the amount of hydrogen p...
متن کاملMultianode Photo Multiplier Tubes as Photo Detectors for Ring Imaging Cherenkov Detectors
The 64-channel Multianode Photo Multiplier (MaPMT) has been evaluated as a candidate for the LHCb Ring Imaging Cherenkov (RICH) photo detectors. We present result from data taken with a 3x3 array of closely packed MaPMTs mounted onto the RICH 1 prototype vessel, exposed to charged particle beams at CERN, and read out at LHC speed. Using a LED light source, we have performed spatial light scans ...
متن کاملResponse of Silicon photo-multipliers to a constant light flux
Silicon Photo-Multipliers (SiPM hence-over) do represent the state of the art for low visible light flux measurements with single photon sensitivity [1,2]. Whether most of the envisaged applications are related to pulsed light [3–5], the response to a constant light field is certainly of interest. This was investigated within RAPSODI (Radiation Protection with Silicon Optoelectronics Devices an...
