Progress in research and development of synchrotron radiation spectroscopy detectors
[ Instrument R&D of Meters Network ] During the first round of Beijing synchrotron radiation dedicated light operation in 2020, the scientific instrument and equipment development project of the Academy of Sciences jointly undertaken by the Institute of High Energy and Microelectronics of the Chinese Academy of Sciences "Based on the high efficiency of multi-element silicon drift detectors Synchrotron Radiation Fluorescence Spectrometer" completed the process test and acceptance. A review team composed of 5 experts from the Institute of Semiconductors of the Chinese Academy of Sciences, the Institute of Biophysics of the Chinese Academy of Sciences, Beijing Normal University, the Qinghai-Tibet Plateau Institute of the Chinese Academy of Sciences and the Institute of Physics and Chemistry of the Chinese Academy of Sciences tested the project technical indicators on the spot and conducted a financial review of the project.
The project technology and process inspection was carried out at the Beijing Synchrotron Radiation Facility (BSRF)-1W2B experimental station. After on-site testing, the developed 8-element spectroscopy detection system met the project requirements and the overall performance has reached the current international mainstream product. Level.
In this round of dedicated light experiments, the multi-element fluorescence spectrometer based on silicon drift detectors completed by the project also initially tested user samples. The spectrometer system is planned to carry out application research in the next round of dedicated light experiments.
