Abstract
Abstract
The Jiangmen underground neutrino observatory (JUNO) is a
neutrino project with a 20-kton liquid scintillator detector located
700-m underground. The large 20-inch PMTs are one of the crucial
components of the JUNO experiment aiming for precision neutrino
measurements with better than 3% energy resolution at 1 MeV. The
excellent energy resolution and a large fiducial volume provide many
exciting opportunities for addressing important topics in neutrino
and astroparticle physics. With the container #D at JUNO Pan-Asia
PMT testing and potting station, the features of waterproof potted
20-inch PMTs were measured with JUNO 1F3 electronics prototype in
waveform and charge, which are valuable for a better understanding
of the performance of the waterproof potted PMTs and the JUNO 1F3
electronics. In this paper, the basic features of the JUNO 1F3
electronics prototype run at Pan-Asia will be introduced, followed
by an analysis of the waterproof potted 20-inch PMTs and a
comparison with the results from commercial electronics used by
container #A and #B.
