Testing a silicon photomultiplier time-of-flight (TOF) system in Fermilab Test Beam Facility

The first results from a time-of-flight beam test of silicon photomultipliers (SiPm) with quartz Cherenkov radiators obtained in the Fermilab Test Beam Facility are discussed. The timing measurement was performed with commercial electronics that were commissioned in the Fermilab SiPm timing facility. The plan for a new time-of-flight system for the test beam facility, with the goal of obtaining a few tens picosecond time resolution is presented.
