Abstract
Micro-channel plate photomultiplier tube (MCP-PMT) is a kind of photosensitive device with single photon detection capability and great time resolution, which is also called Fast-PMT (FPMT). The characteristic of MCP makes the MCP-PMT capable of reaching great spatial resolution with multi-anodes. With the experience of successfully R&D of the 20-inch MCP-PMT, the researchers in IHEP are now developing the multi-anodes FPMT with great time resolution and spatial resolution. By now, the single-anode, 2×2 anodes, 4×4 anodes and 8×8 anodes FPMT prototypes have been successfully produced. With the fast-timing test system, the performance of these prototypes has been tested. The best TTS can reach 76 ps for single photoelectron and 15 ps for multi photoelectrons.
