基于先进超导射频技术的希格斯能LEptoN（HELEN）对撞机
Higgs-Energy LEptoN (HELEN) Collider based on advanced superconducting radio frequency technology
摘要：
这篇Snowmass 2021贡献的论文讨论了基于先进超导射频技术的Higgs-Energy LEptoN（HELEN）$e^+e^-$线性对撞机。拟议中的对撞机提供成本和交流电源的节省，更小的足迹（相对于ILC），并可以在费米实验室建立一个相互作用区域内的网站边界。在250 GeV的初始物理运行之后，对撞机可以升级到更高的光度或更高的能量（高达500 GeV）。如果ILC不能及时在日本实现，那么HELEN对撞机将是在美国建立希格斯工厂的可行选择。
英文摘要：
This Snowmass 2021 contributed paper discusses a Higgs-Energy LEptoN (HELEN) $e^+e^-$ linear collider based on advances superconducting radio frequency technology. The proposed collider offers cost and AC power savings, smaller footprint (relative to the ILC), and could be built at Fermilab with an Interaction Region within the site boundaries. After the initial physics run at 250 GeV, the collider could be upgraded either to higher luminosity or to higher (up to 500 GeV) energies. If the ILC could not be realized in Japan in a timely fashion, the HELEN collider would be a viable option to build a Higgs factory in the U.S.
