The measurement and evaluation of the SiPM PDE for the LACT camera
The Large Ultra-High Energy Gamma-ray Source Stereoscopic Tracking Device (LACT) project will deploy 32 Cherenkov telescopes with a diameter of 6 meters in Haizishan, Daocheng County, Sichuan Province, to conduct precise structural measurements of more than ten ultra-high energy gamma-ray sources discovered by LHAASO.It is used to conduct precise structural measurements on more than ten ultra-high energy gamma-ray sources discovered by LHAASO.Among them, the photon detection efficiency (PDE) significantly affects the response sensitivity of the SiPM camera to weak Cherenkov light. This report conducted a comparative test of the PDE of SiPM samples from different manufacturers using multi-wavelength LED light sources.
