The features of electronics structure of the multichannel scintillation module for the EMMA experiment

A brief description of the developed structural electric diagrams of 16-channel scintillation module for the underground EMMA experiment, the basic characteristics and parameters of the electrical diagrams of this module are presented. Multi-pixel photodiodes operating in a limited Geiger mode are used for photoreadout of the scintillator de- tectors in 16-channel scintillation module. The method of the automatic tuning of the photosensors gain based on the sta- bilization of an average counting rate of the scintillation de- tectors from gamma rays of a natural radioactive background is described.
