Development of a 10 ps level time of flight system in the Fermilab Test Beam Facility

摘要

We describe here the development of a time of flight (TOF) system with 10-20 ps resolution for particle identification in a beam line. The detector resolution also was measured with the start and stop counters close together in the 120 GeV proton beam of the Fermilab Test Beam Facility. We tested both microchannel plate photomultipliers (MCP PMT) and silicon photomultipliers (SiPMs), in both cases using Cherenkov light produced in fused silica (quartz) radiators.
