On December 14-15, 2023, the "Brooke X-ray Diffraction Instrument User Exchange and TOPAS Advanced Training Conference" was successfully held at the Roentgen Laboratory under Shuyun Instrument (Shanghai) Co., Ltd. This training session was hosted by Brook AXS and organized by Shuyun Instrument&Lunqin Laboratory, attracting more than 60 new and old users to register. The application majors of Brook AXS and Lunqin Laboratory gave wonderful presentations and provided targeted answers to the problems encountered by users during use. The two-day training session was enriching and exciting, building a closer bridge of communication and cooperation with customers. Looking forward to seeing you again next time!
