Development of a large area gas photomultiplier with GEM/μPIC
We are developing a new photon detector with micro pattern gaseous detectors. A semitransparent CsI photocathode is combined with 10cm×10cm GEM/μPIC for the first prototype which is aimed for the large liquid Xe detectors. Using Ar+C2H6 (10%) gas, we achieved the gas gain of 10 which is enough to detect single photoelectron. We, then, irradiated UV photons from a newly developed solid scintilla...
متن کاملDevelopment of a Large-Area Aerogel Čerenkov Counter Onboard BESS
This paper describes the development of a threshold type aerogel Čerenkov counter with a large sensitive area of 0.6m to be carried onboard the BESS rigidity spectrometer to detect cosmic-ray antiprotons. The design incorporates a large diffusion box containing 46 finemesh photomultipliers, with special attention being paid to achieving good performance under a magnetic field and providing suff...
