JUNO 20-inch PMT and electronics system characterization using large pulses of PMT dark counts at the Pan-Asia testing platform
View through CrossRef
Abstract
The main goal of the JUNO experiment is to determine the
neutrino mass ordering with a 20 kt liquid-scintillator
detector. The 20-inch PMT and its 1F3 (one for three) electronics
are crucial to realize the excellent energy resolution of at least
3% at 1 MeV. The knowledge on the PMT and 1F3 electronics
response is critical for detector performance understanding. A study
of the JUNO 20-inch PMT and 1F3 electronics system characterization
is presented using large pulses of PMT dark count at the Pan-Asia
testing platform in China. Thanks to its broad amplitude range and
high rate, the large pulse signals are also used to investigate the
PMT after pulse response.
