Description
The PandaX (Particle AND Astrophysical Xenon Experiments) project is a staged xenon-based deep experiment at the China Jin-Ping Underground Laboratory. The PandaX detector is now being upgraded to its next generation, PandaX-20T, which features a sensitive volume of about 20 tons to search for rare events, including the detection of dark matter, solar neutrinos, and neutrinoless double-beta decay.
PandaX-20T is building a high-radiopure and high-efficiency photosensor system. The photosensor system comprises two PMT arrays, including 616 two-inch PMTs on top and 433 three-inch PMTs on bottom with a total photocathode coverage at the 10-m2 level. In this talk, we will present the current status of the PandaX-20T photosensor system, with a focus on the R&D of its frontends, including the development of a novel flex-rigid board, PMT modularization assembly for the system integration, as well as the verification tests of the key components.
