Ambient temperature and beam
- 1. High Energy Accelerator Research Organization (KEK), Tsukuba, Ibaraki (Japan)
Description
KEK's electron-positron injector began operation in 1982 as an electron injector for the PF ring. After repeated expansion and modification, it is currently in operation as an injector for PF, PF-AR, and SuperKEKB. Various improvements have been made to stably supply good quality beams. The temperature of the gallery where the power supply is installed is stabilized by the air conditioning system managed by the facility department. As the beam became more stable through various improvements, it became impossible to ignore the effects of temperature fluctuations on the beam, which had not been an issue up until now. It was found that the temperature change in the upstream part of the A sector has a great effect on the beam stabilization. We report on the measures against temperature fluctuations in the upper sector of A sector. (author)

KEKの電子陽電子入射器は1982年にPFリングの電子入射器として稼働をはじめ、様々な増設、改造を重ね現在はPF、PF-AR、SuperKEKBの入射器として運用中である。これまで良質のビームを安定に供給するために様々な改良を実施して来た。電源等が設置されているギャラリーの温度は施設の空調システムによって管理されているが、ビームが安定になって来るとこれまで問題にされなかった温度変動がビームに与える影響を無視出来なくなった。ここではギャラリーの温度変動がビームに与える影響を調査しその対策を検討したので報告する。(著者)Additional details
