【 摘 要 】

The possibility of determination of plastic scintillation detector characteristics by usage of measurement results and numerical modeling is studied in this paper. One of the main characteristic of scintillation detectors, defining the amplitude of output signal at the particle registration, is light collection that depends on the transparency and reflection coefficient of scintillator. A technique based on a comparison between the signals of particles measured in various places of the scintillator and the results of numerical simulation is suggested. Using experimental data and numerical modeling for the sample laboratory detector, the main characteristics of the scintillator were obtained. This technique can be used for online monitoring of the scintillator properties during the long-lasting space experiments.
