The primary fields of development include nuclear power devices, space equipment, research and medical radiation devices, and nuclear radiation detection is widely used in these fields. Space exploration requires all-weather monitoring of cosmic rays and instant warning of strong pulses, new synchrotron light sources and other national scientific devices require irradiation detectors that are capable of withstanding high-dose irradiation and high-temperature environments for an extended period of time, the development of a new generation of nuclear energy and nuclear medicine applications also imposes new requirements for the charge collection efficiency, anti-irradiation characteristics, charge and positions capacity.
