Experimental studies of scintillation detectors based on WLS fibers

详细

This paper describes the design and presents the results of experimental studies of single-stage and two-stage fiber-optic light collection (FOLC) scintillation detectors based on wavelength-shifting (WLS) fibers. FOLC detectors are designed for the registration of ionizing radiation with a pulse duration of up to 20 μs. The detector design allows one to place photodetectors at a distance of up to tens of meters from the scintillator. The time resolution and sensitivity of FOLC detectors to ⁶⁰Co gamma photons were studied. Experimental studies of FOLC detectors were performed at FSUE All-Russia Research Institute of Automation (VNIIA).
