| Description | In this paper, we discuss the method of setting the optimal working voltage on the photomultipliers of detectors containing thin plastic scintillation materials. These plastic scintillators may additionally include a zinc sulfide ZnS(Ag) layer for the separation of alpha and beta particles. The ionizing radiation on the thin plastic scintillators is not fully absorbed and therefore it is not possible to determine the position of the Compton edge. This is very important for energy calibration. We have proposed a simple method for this purpose and carried out all tests with the newly developed smart frisking probe. The results are presented. |
