Abstract
- North Night Vision Tech. Ltd.(NNVT) supplied 15,000 pieces of 20-inch Microchannel plate photomultiplier tubes (MCP-PMTs) with high detective efficiency and light detection coverage for Jiangmen Underground Neutrino Observatory (JUNO) experiment for neutrino detection. The uniformity of the large-area PMT is a very important parameters, it directly affects the detective efficiency when the light illuminates on the PMT photocathode. The performances including the uniformity of the MCP-PMTs should be tested carefully before transaction and transportation in NNVT. Therefore a facility with high test efficiency and high automation is necessary to be designed and constructed to monitor the uniformity of 20-inch MCP-PMTs. In this paper, we describe and compare three development stages and methods of the uniformity scanning platform and the uniformity result of all MCP-PMTs are presented. [ABSTRACT FROM AUTHOR]
