Abstract
We have developed a 4-channel multi-anode MCP-PMT, SL10, which exhibits good performance of the transit time spread, σTTS≃30ps for single photons with a gain of ∼106 and a peak quantum efficiency of 20% under a magnetic field of ⩽1.5T. The cross-talk among anodes has been extensively studied. We have taken two measures to suppress it: one is to configure the SL10 to an effectively independent four small pieces of MCP-PMT's by segmenting an electrode of the second MCP-layer; the other is to use a constant-fraction discriminator. A remarkable improvement has been achieved.
