The silicon photomultipliers in the detector subsystems of the GlueX experiment

[摘要] The subsystem detectors of GlueX experiment use silicon photomultiplier (SiPM). Around five thousand SiPM's in total uses in the detectors of experiment. The detectors operate in condition of load level 2MHz and up to 104pixels «fired» with ∼0.3ns time resolution. The list of such detectors: the tagger microscope, the pair spectrometer, the start counter which surrounded the liquid hydrogen target; the electromagnetic barrel calorimeter to measure energy and direction of secondary photons comes from the target. We present the results of the time resolution measurements and the relaxation time measurements for two SiPM types in experimental conditions.
