Title: The Status of the MCP-PMT R&D in China
Abstract content The JUNO (Jiangmen Underground Neutrino Observatory) designed to build an underground lab on the location of JiangMen in south China as a generic underground national lab for many applications. The new promising neutrino programs request the higher performance of the detectors. It is proposed to increase the photoelectron detection efficiency of the PMT used in neutrino experiment. The researchers in IHEP designed a new type of MCP-PMT. The small MCP unit instead of the large Dynode, the transmission photocathode and the reflection photocathode were assembled in the same glass shell to form nearly 4 pai photocathode effective area to enhance the efficiency of the photoelectron detecting. Some researchers and engineers in institutes and companies in China come together to manufacture and research this type of PMT based on the MCPs. After two years R&D work, several 8 inch prototypes were produced and there performance was carefully tested in our Lab. The MCP-PMT performance test system was built in our Lab for better performance test. The characteristics of the photocathode were carefully researched by testing the I-V curve, the QE, and the QE-map for the 8 inch area photocathode uniformity. Also we measured the charge spectrum to confirm its ability for the single photoelectron spectrum. More simulation and experiment work have already done to develop an 8 inch prototype module for the MCP-PMT designed in IHEP, and the detailed will be described in this formal manuscript.
