Description

technical field [0001] The invention relates to the technical field of nuclear spectroscopy and nuclear electronics, in particular to a high-speed parallel multi-channel multi-channel data system for nuclear spectroscopy and nuclear electronics. Background technique [0002] In nuclear spectroscopy measurement, multi-channel analyzers are measurement units that record and analyze pulse information of nuclear physics events, and are divided into single-channel multi-channel (multichannel) analyzers and multi-parameter (multi-parameter) multi-channel analyzers. Multi-parameter and multi-channel measurement is an important part of nuclear spectroscopy experiments and measurements, and is widely used in various nuclear physics experiments and nuclear analysis techniques. Its core principle is to record the energy and time information of pulse signals from various channels (channels) at the same time or time-sharing, and analyze, process and record the data to obtain the physical...
