Description

The High Energy Accelerator Research Organization (KEK) operates two synchrotron radiation experimental facilities: the 2.5 GeV PF ring and the 6.5 GeV PF Advanced Ring (PF-AR). In FY2022, the PF ring will continue to upgrade the beam orbit stabilization system and started to upgrade the low power RF (LLRF) system. In the PF-AR, various beam tunings are performed toward full-scale user operation at the instrument development test beamline (AR-TBL). In this paper, the present status of the PF ring and the PF-AR operation will be reported and presents a new concept of hybrid light source that combines the advantages of a superconducting linac and a storage ring.

Abstract (Japanese)

大学共同利用機関法人高エネルギー加速器研究機構(KEK)の放射光実験施設(フォトンファクトリー:PF)は、2.5GeV PFリングと6.5GeV PFアドバンストリング(PF-AR)の2つの放射光専用リングを運転している。両リングともに稼働から約40年経過しており、各種装置の老朽化が顕著になってきているが、随時対策を講じながら故障率1%台の安定な運転を維持している。2022年度、PFリングでは、ビーム軌道安定化システムの高度化の作業を継続するとともに、低電力RF(LLRF)システムの更新などを進めている。PF-ARでは、測定器開発テストビームラインでの本格的なユーザー運転に向けた各種ビーム調整が順調に進行している。本年会では、PFリングとPF-ARにおける運転の現状について報告するとともに、次期計画として検討をすすめている超伝導加速空洞と蓄積リングを組み合わせた「ハイブリッドリング」について紹介する。(著者)
