2015年是爱因斯坦广义相对论发表一百周年，联合国大会将其命名为国际光和光基技术年。因此，现在讨论扩大目前欧洲核子研究中心研究计划的可能性是及时的，包括一个新的组成部分的基础上，一个新的概念的光源，可以铺平道路，走向多用途伽马工厂。建议的光源可以通过使用现有加速器的基础设施在CERN实现。它可以将目前运行的光源的强度极限至少提高7个数量级，达到10^17光子/秒的量级，在1 < Ephoton < 400 MeV的特别有趣的伽马射线能量域中。这一领域是自由电子激光光源所无法达到的。经能量调整的准单色伽马射束以及伽马射束驱动的高强度极化正电子、极化μ子、中子和放射性离子次级射束将构成拟议伽马工厂的基本研究工具。伽马工厂可以在未知的基础物理学和工业应用领域的广阔领域开辟新的研究机会。它将为TeV能级μ介子对撞机和基于极化μ介子束的中微子工厂提供前所未有的极化μ介子次级束流，从而加强CERN在高能前沿研究领域的主导地位。
This year, 2015, marks the centenary of the publication of Einsteins Theory of General Relativity and it has been named the International Year of Light and light-based technologies by the UN General Assembly. It is thus timely to discuss the possibility of broadening the present CERN research program by including a new component based on a novel concept of the light source which could pave a way towards a multipurpose Gamma Factory. The proposed light source could be realized at CERN by using the infrastructure of the existing accelerators. It could push the intensity limits of the presently operating light-sources by at least 7 orders of magnitude, reaching the flux of the order of 10^17 photons/s, in the particularly interesting gamma-ray energy domain of 1 < Ephoton < 400 MeV. This domain is out of reach for the FEL-based light sources. The energy-tuned, quasi-monochromatic gamma beams, together with the gamma-beam-driven, high intensity secondary beams of polarized positrons, polarized muons, neutrons and radioactive ions would constitute the basic research tools of the proposed Gamma Factory. The Gamma Factory could open new research opportunities in a vast domain of uncharted fundamental physics and industrial application territories. It could strengthen the leading role of CERN in the high energy frontier research territory by providing the unprecedented-brilliance secondary beams of polarized muons for the TeV-energy-scale muon collider and the polarized- muon-beam based neutrino factory.
