摘要：
A digital pulse processing system convenient for high rate gamma-ray spectroscopy with NaI(Tl) detectors has been designed. The new programmable logic device has been used for implementation of dedicated high-speed pulse processor, as the central part of the system. The processor is capable to operate at the speed of fast ADC, preserving maximum throughput of the system. Special care has been taken to reduce the distortion of energy spectrum caused by pile-up at high-count rates. The developed system is highly flexible, and the parameters of its operation can be changed in software. The performance of the system was tested for high counting rate of 400 000 s(-1).
