Counting Characteristics of the Registration System for the Baksan Experiment on Sterile Transitions

摘要

— Counting characteristics of the system for recording rare events of the_(71)Ge decay in the radiochemical gallium Baksan Experiment on Sterile Transitions (BEST) are presented. Events are recorded simultaneously along eight counting channels in the energy range 0.3–16 keV, which include_(71)Ge decays in the region of L and K peaks with a total efficiency of up to 75%. The data analysis is based on the recording of the full shape of the leading edge of the charge pulses using a digital oscilloscope.
