METHOD FOR PULSE SHAPE REGULATION AND DISCRIMINATON IN A NUCLEAR SPECTROSCOPY SYSTEM.

摘要

The present invention is based on a digital pulse sampling and detection technique which samples the (nuclear) pulse train at a constant frequency asynchronously with the actual pulses, which occur at random times. The fact that many samples are available for each pulse allows many pulse train analysis operaton, such as: 1) pulse integration (area determination under pulse), 2) pulse shape discrimination, 3) pile-up rejection and 4) time or arrival determination (multiscaler analysis) which traditionally were done through complex analog circuits to be done in a compact digital arrangement. This invention deals with the first 3 aspects of digital pulse train analysis.
