The status of the R&D of Ultra Fast 8 times 8 Readout MCP-PMTs in IHEP

Abstract

Based on the development of the 20-inch large-area MCP-PMT, the research of a small, ultra-fast MCP-PMT is carried out with the cooperation of Institute of High Energy Physics (IHEP), Chinese Academy of Sciences and Northern Night Vision Technology Co., LTD (NNVT). The structural simulation and optimization of the fast-time PMT was first performed by a Monte Carlo-based approach. Accurate measurements of the time performance of greatest interest are then tested and validated. IHEP and NNVT have successfully developed single-anode, 4 times 4-anode and 8 times 8-anode sample tubes suitable for different application scenarios. While maintaining the single-photon detection capability of the sample tube, the limiting time resolution of the
