Description

technical field [0001] The invention belongs to the technical field of nuclear radiation detection, and in particular relates to a multi-parameter time synchronization spectrometer data acquisition system and its application. Background technique [0002] Current nuclear physics tests, nuclear data parameters, and various nuclear technology applications often require the simultaneous use of multiple types of nuclear radiation detectors to achieve specific measurement functions, including high-purity germanium semiconductor detectors and inorganic scintillator detectors , liquid scintillation detectors and gas detectors. Different types of detectors play different roles in the measurement system. Some detectors such as high-purity germanium detectors (HPGe) mainly measure their high-resolution energy spectra, and some detectors (liquid Flash) measures the arrival time of its rays, and some detectors (NaI) mainly measure Compton scattering; for this reason, it is necessary to ...

Problems solved by technology

[0003] The data acquisition and acquisition system of the traditional nuclear radiation detection system is mainly based on the energy spectrum acquisition mode. Obviously, this mode can only be used for specific requirements. When the requirements change slightly, such as changing from a coincidence system to an anti-coincidence system, Need to change the hardware and software system design to meet the requirements
