Cryogenic tests of time of flight and Scintillating Fibre Tracker prototypes read out by SiPMs for the AMS-100 experiment

Year: 2025

Type: article

Abstract: The AMS-100 Experiment, the next generation magnetic spectrometer in space, will use plastic scintillators read out by silicon photomultipliers (SiPM) as a time of flight (ToF) detector. The ToF will be operated in vacuum at cryogenic temperatures. The Scintillating Fiber Tracker (SciFi) for AMS-100 and the planned LHCb Upgrade II will use scintillating fiber mats read out by SiPM arrays. The SiPMs will be operated in vacuum at cryogenic temperatures. We will present time resolution and signal shape measurements with a ToF-prototype in the temperature range of 303 K to 77 K. Long term tests of a ToF prototype in vacuum will be shown. Thermal studies and light yield measurements of a SciFi tracker prototype at room temperature and at 77 K in vacuum will be presented.
