欧洲核子研究中心的多用途伽马工厂方案依赖于使用部分剥离离子束(PSI)作为其光源的驱动器，而不是电子束。如果这样的束流能够被成功地存储在大型强子对撞机的环中，在1≤Eγ≤400 MeV的LHC-ray能域内，可以获得高达1017光子/S的通量。只要多TeV电子束不可用，基于自由电子激光的光源就达不到这个能量域。欧洲核子研究中心伽马工厂的提议有可能将目前逆康普顿散射源的强度极限提高七个数量级。2017年，欧洲核子研究中心加速器复合体通过产生一种新的氙离子束展示了其灵活性。基于这一成就，伽玛工厂研究小组要求进行专门研究。它的目的是在SPS中注入和加速部分剥离的氙离子(129Xe39+)，测量它们的寿命，并确定导致PSI束流损失的过程的相对强度。鉴于计划于2018年进行的含铅防扩散措施束流的未来研究，本投稿中提出的研究是一个准备步骤。
The CERN multipurpose Gamma Factory proposal relies on using Partially Stripped Ion (PSI) beams, instead of electron beams, as the drivers of its light source. If such beams could be successfully stored in the LHC ring, fluxes of up to 1017 photons/s, in the γ-ray energy domain of 1 ≤ Eγ ≤ 400 MeV could be achieved. This energy domain is out of reach for the FEL-based light sources as long as the multi TeV electron beams are not available. The CERN Gamma Factory proposal has the potential of increasing by seven orders of magnitude the intensity limits of the present Inverse Compton Scattering sources. In 2017 the CERN accelerator complex demonstrated its flexibility by producing a new, xenon ion beam. The Gamma Factory study group, based on this achievement, requested special studies. It aimed to inject and to accelerate, in the SPS, partially stripped xenon ions (129Xe39+) measure their lifetime, and determine the relative strength of the processes responsible for the PSI beam losses. The study presented in this contribution was a preparatory step in view of the future studies programmed for 2018 with lead PSI beams.
