Beijing Spectrometer III is a large-scale universal detector working on the Beijing electron-positron collider. It is responsible for high-energy particle case detection and signal sampling, amplification, trigger selection, and accurate measurement of physical parameters. Its main mechanical structure is 9 meters high, 11 meters long and 6 meters wide, with a total weight of 650 tons. As an extremely complicated system engineering, the main structure of Beijing Spectrometer III is quite difficult in terms of design difficulty and processing and assembly. According to the relevant person in charge of the project, the successful construction of the main mechanical structure of Beijing Spectrometer III has not only become a typical example of the joint research institutes and enterprises to jointly develop major scientific research equipment, but also become a major renovation project of Beijing Electron and Negative Electron Collider. The important milestone marks a major step forward for China's heavy machinery manufacturing industry towards high precision and high complexity.
It is reported that due to the progress of the main project, it is expected that in March 2007, Beijing Spectrometer III will be successfully built.
The main mechanical structure of Beijing Spectrometer III was successfully constructed.
After more than two years of hard work by the Institute of High Energy Physics of the Chinese Academy of Sciences and CITIC Heavy Machinery Co., the main mechanical structure of the Beijing Spectrometer III detector was successfully developed, and an appraisal acceptance meeting was held today. The appraisal committee of Xu Jichu, the academician of the Chinese Academy of Sciences and the honorary president of the Institute of Mechanical Science, believes that the project meets all the requirements of Beijing's third-generation new detector, Beijing Spectrometer III, and the overall performance of the Beijing Spectrometer III mechanical system. The main technical indicators have reached the advanced level of international contemporary similar equipment.
