PRELIMINARY RESULTS OF PLASTIC SCINTILLATORS DETECTOR READOUT WITH SILICON PHOTOMULTIPLIERS FOR COSMIC RAYS STUDIES

摘要

A significant advance in the field of photodetection has been registered in the past few years thanks to the development of a new class of silicon devices, the Silicon Photomultipliers (SiPMs). With a high gain (10~5-10~6), very good single photon detection resolution, fast counting, low-bias voltage (～70 V) and a low price, these devices could become an alternative to traditional PMTs in many applications. Providing a large, proportional signal for low to moderate photon flux, SiPMs are ideal for low light intensity measurements, such as gamma ray astronomy or underground experiments. In this study, we analyze the possibility of implementing this technology on a scintillator detector for cosmic ray showers muonic component measurements in an underground medium. Some preliminary results are presented and some conclusions are drawn.
