Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Experimental determination of the radiometric and spectrometric characteristics for the detection blocks BDRS-05R and BDRS-05R1 Volkov S.V., Volodin V.P., Andrianov T.V. The article shows the structure, characteristics of the two detection blocks (DB), implemented on the base of the scintillation detectors NaI(Tl) 40?40 mm and 63?63 mm, and additionally the main methods of these characteristics determination while DB operation within the detection units, operating with the single-board spectrometer of SBS-79 type, which is provided by the high-voltage programmable control functions at the photo-multiplier tube and the peak stabilization system.
