The improvement of 20" MCP-PMT for neutrino detection

For the next generation neutrino experiment, the MCP-PMT collaboration group has done a lot of work in China. After years of hard work, we have developed 20" MCP-PMT. The MCP-PMT has large sensitive area, high quantum efficiency, high gain and large P/V value for good photon counting performance. The high detection efficiency of 20" MCP-PMT will be used in neutrino detection, and we have got an order for 75% of the PMTs required for neutrino detection. To this end, the MCP-PMT collaboration group also completed the mass production line and batch test system in Nanjing. This presentation will introduce the improvement of 20" MCP-PMT for neutrino detection.
