A 5 ps TOF-counter with an MCP-PMT

We measured the timing resolution of TOF counters by means of Cherenkov-light detection with a Micro-Channel Plate Photo-Multiplier Tube, and attained sigma(TOF) = 6.2 ps using 3 GeV/c pion-beams with a readout electronics of 4.1 ps resolution. The optimum radiator thickness was examined and the detectable number of photo-electrons was analyzed. (c) 2006 Elsevier B.V. All rights reserved.
