Nuclear Detector Group
Brief Introduction
Nuclear physics experiment not only promotes the development of nuclear detector technology, but also puts forward new requirements for related detector technology and electronics. Established in 2019, the nuclear detector group integrates the original gas detector group, the solid detector group and the crystal detector group. Based on the platform of the Institute of modern physics of the Chinese Academy of Sciences, it makes full use of professional advantages and strengthens cross application. Focusing on the research of detector system needed in nuclear physical experiments, it has established high-quality platforms for scientific research and talents cultivation.
The main platforms are as follows:
1. Gas detector experiment platform
The gas detector research team is engaged in the research and development of gas nuclear radiation detector. Researchers focus on the development and performance test of the traditional gas detector and the new micro-pattern gas detector，aiming to enhance the ablity of R&D and provide technical support.for nuclear physics experiments.
The platform covers an area of more than 500 square meters, including the detector test room, the detector assembly room and 10000 class super clean room. It has equipment for the development and detection of gas detectors, and can carry out research work such as the development and production of advanced detectors, joint debugging and testing of gas detectors and other detectors, online acquisition, simulation, analysis and processing, etc.
2. Solid state detector experimental platform
The solid state detector research team is mainly engaged in the research and development of nuclear radiation detectors, providing a large number of gold silicon surface barrier semiconductor detectors and lithium drift detectors for nuclear physics experiments and space exploration.
The team has a complete microelectronics process laboratory, measuring equipment required for testing detectors and supporting back-end electronics system, such as 4-inch microelectronics process line, electrical and optical characteristics measuring equipment for semiconductor materials and devices, electronic system for detector test.
3. Crystal detector experiment platform
Combined with the requirements of nuclear detector development and the application of material modification, the preparation and performance test of crystal materials are explored. And the crystal material is applied to the device preparation to develop a high-performance radiation detector.
