118 ACTIVITY REPORT 2021 User Statistics From 1994 to 2021, the total number of beamlines opened to general users has increased from 3 to 37, comprising 22 TLS beamlines, 2 Taiwanese beamlines at SPring-8, and 13 TPS beamlines (see Beamline Status on page 122). During year 2021, user statistics were inevitably affected by the global health crisis, COVID-19 pandemic. The User Administration & Promotion Office (UAO) issued 601 new user cards, and provided services to 2,197 users coming from 109 affiliations (including 88 users from 53 foreign institutions) to use the above 37 NSRRC beamlines. Altogether, 560 proposals led by 356 principal investigators were performed, involving 1,397 experiment runs and 9,593 user runs (visits). The overall NSRRC beamtime (including SP 44XU*) allocated to users, excluding beamline maintenance and training courses, was 3,420 shifts for TPS, 11,517 for TLS, and 1,050 for SPring-8 (including 9 shifts for SP 44XU). Each shift consists of 8 consecutive hours. Most beamtime schedules of Taiwan-contract beamlines at SPring-8 and the neutron program were cancelled or conducted by using mail-in services due to border controls imposed by many nations to prevent the spread of COVID-19. In total, 120 master’s theses and 28 doctoral dissertations utilizing NSRRC facilities were completed in 2021 (see Appendix). Operational data on beamlines/experimental stations and users are summarized in the following figures. *Note: Institute for Protein Research, Osaka University (IPR-Osaka) and NSRRC have established a long-term collaboration in protein structural research aiming to combine the expertise of both sides and to access each other’s facilities when needs arise. IPR-Osaka offers beamtime of its contract beamline SP 44XU at SPring-8 to Taiwanese users selected by the NSRRC to study large macromolecular assemblies and membrane proteins.
