Description

Modern tasks of very high energy gamma-ray astronomy and astrophysics require the effective and secure record of PMT signals from EAS Cherenkov lighting in the wide energy range from hundred GeV up to some hundred TeV, thus the more than 1000 dynamic range and low noise electronics are required for these purposes. Here we present the modern multi-channel analog-to-digital converter BPA-8 developed on the base of a low power, high speed, 16-bit analog device with high amplitude resolution. The developed and created converters BPA-8 together with data acquisition system managed with intellectual crate-controller K-167 which controls the equipment, using all control and measuring modules allow to record PMT signals with high accuracy and efficiency for the further precise analysis and reliable extraction of weak gamma-ray emission from astrophysical objects.
