DESCRIPTION:Speakers: Alexander Shikhin (BNO INR RAS)\nRegistration system
 s of rare events from $^{71}$Ge decay in radiochemical gallium experiments
  SAGE and BEST are presented\, where miniature proportional counters are u
 sed as detectors. The registration of the events is provided by eight coun
 ting channels simultaneously in the energy range of 0.4-15 keV which inclu
 des the $^{71}$Ge decays in the region of the L and K peaks with total eff
 iciency up to 75%. Data analysis is based on full charge pulse shape recor
 ding using digital oscilloscope. Effective background discrimination is ba
 sically obtained due to low noise ($$100 MHz) of the system electronics. T
 he design and main\nparameters of base components of the registration syst
 ems\, description of electronics and comparison of their electrical and co
 unting characteristics are given.\n\nhttps://indico.particle.mephi.ru/even
