Abstract :
In this article we show the latest results on the characteristics of the MRS (metal/resistor/semiconductor) photodiode. They include measurements of noise vs. threshold characteristics, noise frequency and signal amplitude dependence on the applied voltage and temperature and irradiation dose, and stability as a function of time. The photoelectron separation for this sensor is measured using a signal from a light emitting diode (LED). The response of the photodetector to light from the extruded 5 mm thick long strips of scintillator is studied using cosmic ray muons. Also, fiber-sensor alignment effects were studied. The results are promising and illustrate the potential use of MRS as photosensors in wide range of detectors.
