Timing and cross-talk properties of BURLE multi-channel MCP PMTs

We report on studies of the two types of BURLE multi-anode micro-channel plate (MCP) PMTs; one with 64 channels and 25 μ m pores and the other with four channels and 10 μ m pores. Possible applications of these tubes are for RICH detectors and time-of-flight counters. We have investigated their timing properties and cross-talk. The origin of the cross-talk between the channels was investigated by studying the correlations between signals on neighbouring pads, their amplitudes and time of arrival. We have also studied the influence of cross-talk on timing and spatial resolution.
