伽玛工厂计划建议使用部分剥离离子(PSI)束作为新型高强度光子源的驱动器。作为正在进行的超越对撞机物理研究的一部分,CERN 已使用 PSI 光束进行了初步光束测试。 2018 年 7 月 25 日,带有一个剩余电子的铅离子 (208Pb81+) 首次被注入 LHC 中并被加速。在建立几个 208Pb81+ 束的注入和循环后,在 6.5 TeV 质子当量能量下可以建立约 50 小时的光束寿命。本文描述了光束测试的设置和所做的观察。
The Gamma Factory initiative proposes to use partially stripped ion (PSI) beams as drivers of a new type of high intensity photon source. As part of the ongoing Physics Beyond Collider studies, initial beam tests with PSI beams have been executed at CERN. On 25 July 2018 lead ions with one remaining electron (208Pb81+) were injected and accelerated in the LHC for the first time. After establishing the injection and circulation of a few 208Pb81+ bunches, beam lifetimes of about 50 hours could be established at 6.5 TeV proton equivalent energy. This paper describes the setup of the beam tests and observations made.
