【 摘 要 】

The Superconducting RF Test Facility and the compact Energy Recovery Linac are accelerator facilities at KEK that employ 1.3 GHz superconducting cavities fabricated using niobium. They should be cooled with liquid He at 2 K, for which cryogenic systems were developed at KEK. Home-made control systems were also introduced for stable and effective operation of the 2 K cryogenic systems. The performance of these cryogenic control systems has been improved in accordance with each beam operation.
