Description

This article describes the configuration and heat loads of the large-scale helium refrigeration system for the superconducting cavities utilized for the TRISTAN and KEKB Factory accelerators. The control system of the refrigeration system is also introduced. The fatal failures of the refrigeration system during the past long-term operation are summarized to entice discussions on future stable operation of the refrigeration system, since the refrigeration system will also be used for the SuperKEKB superconducting cavities.
