论文摘要
该报告描述了$γγ$ Higgs工厂的设计，其中62.8 GEV电子梁与1 KeV X射线游离电子激光（XFEL）梁碰撞，以产生62.5 GEV光子的碰撞光束。希格斯玻色子的生产率为34,000个希格斯玻色子，每$ 10^7 $第二年，大致与ILC Higgs率相同。电子加速器基于冷铜分布式耦合（C $^3 $）加速器技术。 XFEL的0.7 J脉冲能比电流软X射线FEL的脉冲能量增加了300倍。讨论了设计挑战，以及R \＆D，以解决包括示威者在内的问题。
This report describes the design of a $γγ$ Higgs factory in which 62.8 GeV electron beams collide with 1 keV X-ray free electron laser (XFEL) beams to produce colliding beams of 62.5 GeV photons. The Higgs boson production rate is 34,000 Higgs bosons per $10^7$ second year, roughly the same as the ILC Higgs rate. The electron accelerator is based on cold copper distributed coupling (C$^3$) accelerator technology. The 0.7 J pulse energy of the XFEL represents a 300-fold increase over the pulse energy of current soft x-ray FEL's. Design challenges are discussed, along with the R\&D to address them, including demonstrators.
