Description
In July 2025, all superconducting cavity strings for the Heavy Ion Accelerator Facility (HIAF) were successfully delivered after a strict cleanroom assembly process. Supported by a rigorous process quality management system, this work achieved zero-defect physical delivery and met the accelerator’s performance requirements. A small number of unexpected issues, such as helium tank leakage, were detected in later stages, but effective and well-documented mitigation measures were quickly adopted to fully resolve them. This report summarizes the successful clean assembly procedures and draws important engineering lessons from these special cases.
It also introduces IMP’s pioneering research on automated assembly technology for superconducting radio-frequency (SRF) cavities in a cleanroom environment. Key steps from conventional manual operations, including cavity transportation, automated handling, precise nut placement, and reliable fastening, have been systematically analyzed and modularized. The main technical challenge is the smooth integration of these individual steps into a complete, fully automated workflow.
