Set of electronic devices based on semicustom integrated systems for recording of pulse low-level visible radiation POLOSA

  The set includes integral microcircuit of amplifier-discriminators AD-1.14, AD-1.15, AD-1.16 and
   AD-1.17 of DOM-type.

   Purpose
   The set is designed for registration of signals from multi-pixel avalanche photodiodes of MAPD-1
    type, that are used as photoelectric receptors of scintillation detectors in counter hodoscopes.

    It can be used in muonic systems of experiments “PANDA and “NICA-MPD. Integral microcircuits
   correspondingly consist of amplifiers Ampl-1.14, Ampl-1.15, Ampl-1.16, Ampl-1.17 and
   comparators Disc-1.4 (for AD-1.14, AD-1.15, AD-1.17) and Disc-1.16 (for AD-1.16).
