WebPMT Testing Program The Particle Astrophysics group plays pivotal roles in many key aspects of the experiment. The group ran a two-year testing operation in which all 494 PMTs were tested multiple times at both room and LXe temperatures to ensure consistency and durability in the PMTs, as well as to fully characterize each individual PMT response. WebMar 1, 2013 · The PMTs contribute backgrounds in the form of gamma rays and neutrons produced by radioactive decay, as well as neutrons from ( α, n) reactions in PMT materials. Neutron backgrounds are of particular importance to dark matter detectors due to their similarity to a WIMP nuclear recoil signal. WebAug 1, 2024 · From the full detector Monte Carlo (MC) simulation, the PMT glass has one of the largest contribution to the natural radioactive background due to its large mass. … pvda rijnland
