摘要：
Gamma Factory计划提出在欧洲核子研究中心（CERN）开发新型研究工具，具体方式是在超级质子同步加速器（SPS）和大型强子对撞机（LHC）储存环中产生、加速并储存高相对论性的部分剥离离子束。通过用激光激发储存离子的电子自由度，对沿离子传播方向出射的峰值次级辐射进行适当准直后，就能产生高能窄带光子束。这些光子束的强度高达每秒$10^{17}$个光子，在能量可达400 MeV的备受关注的$\boldsymbol{\u03b3}$射线能区，其强度比当前运行的光源高出数个数量级。本文综述了利用主束对储存环中循环的部分剥离离子开展光谱研究的潜在机遇，以及利用次级高能光子束带来的原子物理学研究机遇。Gamma Factory将推动光谱学领域的突破性实验，为检验自然界基本对称性提供全新途径。
英文摘要：
The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating and storing highly relativistic, partially stripped ion beams in the SPS and LHC storage rings. By exciting the electronic degrees of freedom of the stored ions with lasers, high-energy narrow-band photon beams will be produced by properly collimating the secondary radiation that is peaked in the direction of ions' propagation. Their intensities, up to $10^{17}$ photons per second, will be several orders of magnitude higher than those of the presently operating light sources in the particularly interesting $γ$--ray energy domain reaching up to 400 MeV. This article reviews opportunities that may be afforded by utilizing the primary beams for spectroscopy of partially stripped ions circulating in the storage ring, as well as the atomic-physics opportunities afforded by the use of the secondary high-energy photon beams. The Gamma Factory will enable ground breaking experiments in spectroscopy and novel ways of testing fundamental symmetries of nature.
