      At the Spallation Neutron Source (SNS), the proton accumulator ring concentrates technical risk in the injection region, where the electron catcher (e-catcher) removes secondary electrons generated during H⁻ stripping to protect nearby components and maintain stable operation. Following Proton Power Upgrade (PPU) modifications, the e-catcher failed on first beam operation due to insufficient...

      The accelerator facility in Harima consists of the CW ring-type light source “SPring-8,” which has been in operation for more than 30 years, and the relatively new X-ray free-electron laser (XFEL) “SACLA.” The aging SPring-8 is scheduled to shut down in the summer of 2027 and undergo a massive upgrade involving a complete replacement of its accelerators, transforming it into...

    3. 85. The Interface Is a System: Managing Boundaries for Reliable Integration

      Integrated Reliability across accelerator sub-systems – Importance of robust interface definition
      Oral

      Modern accelerator facilities are increasingly developed through distributed collaborations involving multiple teams, institutions, and external suppliers. While individual subsystems are often designed to high technical standards, many integration issues originate at the interfaces between them rather than within the subsystems themselves.
