论文摘要
具有现代标准激光器的最佳状态，只有以光子光度为代价，高能量E电子E电子梁的高能量$γγ$ colling只能比C.M.的光子乘客低10倍，即低10倍。低于0.5 TEV的能量。对于现有的最新激光器，X = 4.8的乐观上部能量限制是小于250 GEV的电子束。该雪地21贡献的论文显示了自由电子激光器（FEL）如何为高能量和高光度$γγ$ collider铺平道路。我们介绍并评估了一项概念设计研究，其波长为2.4 $ $ m $ m和2至40的X因子的FEL，以最大程度地提高$γγ$ collider的发光度，作为0.5 TEV至10 TEV C.M.的第二相互作用区域。 $ e^+e^ - $ COLLIDERS。
With the best of modern standard lasers, high-energy $γγ$ colliders from electron beams of E larger than 250 GeV are only possible at the expense of photon luminosity, i.e. 10 times lower than for photon colliders at c.m. energies below 0.5 TeV. For existing state-of-the art lasers, an optimistic upper energy limit for x=4.8 is an electron beam of less than 250 GeV. This Snowmass21 Contributed Paper shows how Free Electron Lasers (FEL) pave the way for High Energy & High Luminosity $γγ$ colliders. We present and assess a conceptual design study of a FEL with wavelength of 2.4 $μ$m and an x-factor in the range of 2 to 40, to maximize the luminosity of a $γγ$ collider as second interaction region of 0.5 TeV to 10 TeV c.m. $e^+e^-$ colliders.
