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, 4x4-anode and 8x8-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 sample tube can reach 30ps.
