Abstract
This article describes design of a new multichannel acquisition system with photomultiplier tubes (PMTs). The system allows mean current measurement and photon counting for 2 PMT coincident operation. In order to obtain very high dynamic range, signal from the PMT is sampled by 14 bit resolution ADC and analyzed by high speed window discriminators and constant fraction discriminators (CFD). Output data is processed in the FPGA and transmitted to the embedded computer. The system has been developed for astrophysical and high energy physics research.
