伽马工厂计划提议在欧洲核子研究中心开发新的研究工具，通过在SPS和LHC存储环中产生、加速和存储高度相对论性、部分剥离的离子束。利用激光激发存储离子的电子自由度，适当准直离子传播方向上的峰值二次辐射，可产生高能量窄带光子束。它们的强度高达每秒1017个光子，将比目前在特别有趣的γ射线能量域中达到400 MeV的光源高出几个数量级。本文综述了利用主光束对在存储环中循环的部分剥离离子进行光谱分析所提供的机会，以及利用次级高能光子光束所提供的原子物理机会。伽马工厂将使光谱学的突破性实验和测试自然基本对称性的新方法成为可能。
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 1017 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 made possible 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.
