Muons detector

Astrophysics studies of the most violent phenomena involve the use of observational instruments different from classical astronomy. These instruments use nuclear physics technics. During this training course, I developed a muons detector for the CAT (Cerenkov Array at Themis) camera. The sign of the muon Cerenkov light through the CAT camera is a ring or a part of a ring whose shape and instensity are well known. The rings study is used to calibrate the photomultiplicator and mirror set of the CAT camera, to measure the trigger efficiency, and to characterize the muons background noise. I built this muons detector (drum shape) to sign their presence.

In this study, photomultiplicators have been characterized using specific nuclear physics electronics (CAMAC electronics). I also developed an electronic signals treatments code and a numerical simulation code to evaluate the muons rate on the drum detector.
