Description
The Jiangmen underground neutrino observatory (JUNO) is a neutrino project with a 20-kton liquid scintillator detector located at 700-m underground. As a key component of JUNO detector, the performance of 20-inch PMTs has a significant impact on the energy and timing measurement and the vertex reconstruction of physical analysis. 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 this poster, the system schema and testing process of the container #D will be introduced. The characteristics of potted 20-inch PMTs will be shown and compared with tested bare PMTs in such as the amplitude, gain, timing and so on, which are valuable for better understanding on the performance of the JUNO waterproof potted PMTs and the future JUNO 1F3 electronics.
