The TORCH time-of-flight detector
نویسندگان
چکیده
TORCH is a large-area time-of-flight (ToF) detector, proposed for the Upgrade-II of LHCb experiment. It will provide charged hadron identification over 2–20 GeV/c momentum range, given 9.5 m flight distance from LHC interaction point. To achieve this level performance, 15 ps timing resolution per track required. A prototype module having 1250×660×10 mm3 fused-silica radiator plate and equipped with two MCP-PMTs has been tested in 8 CERN test-beam. Single-photon time resolutions between 70–100 have achieved, dependent on beam position radiator. The measured photon yields agree expectations.

Beam test of a Time-of-Flight detector prototype
We report on results of a Time-of-Flight, TOF, counter prototype in beam tests at SLAC and Fermilab. Using two identical 64-pixel Photonis Microchannel Plate Photomultipliers, MCP-PMTs, to provide start and stop signals, each having a 1 cm-long quartz Cherenkov radiator, we have achieved a timing resolution of σSingle_detector ~14 ps.

Development of a Time-of-Flight detector for the Rare-RI Ring project at RIKEN
We have tested the timing properties of several thin plastic scintillators (10-500 μm) designed for the Rare-RI Ring project at the RI Beam factory. The experiments were performed at the heavy-ion synchrotron facility, HIMAC (Heavy Ion Medical Accelerator in Chiba), using a Xe beam with an energy of 200 MeV/nucleon. The scintillation light was read out by fast-timing photomultipliers through st...
