论文摘要
我们将圆形能量回收对撞机（CERC）作为一种高能高亮度电子 - 峰值对撞机的替代方法，以基于两个存储环（具有100 km圆周或两个大型线性加速器）的两个存储环。使用位于同一规模的100公里隧道中的能量恢复Linac（ERL），将允许大幅度减少梁的能量损耗，从而减少功耗，同时提供较高的发光度。它还为将质量中心（cm）能量扩展到500 GEV的路径，这将使双基因生产，甚至达到600 GEV，用于生产和测量最高的Yukawa耦合。此外，这种方法不仅可以回收能量，而且还可以回收颗粒。此功能打开了完全极化电子和正电子束的可能性。
We present a Circular Energy Recovery Collider (CERC) as an alternative approach for a high-energy high-luminosity electron-positron collider to current designs for high-energy electron-positron colliders either based on two storage rings with 100 km circumference or two large linear accelerators. Using Energy Recovery Linacs (ERL) located in the same-size 100 km tunnel would allow a large reduction of the beam energy losses, and therefore a reduction of the power consumption, while providing higher luminosity. It also opens a path for extending the center-of-mass (CM) energy to 500 GeV, which would enable double-Higgs production, and even to 600 GeV for production and measurements of the top Yukawa coupling. Furthermore, this approach would allow recycling of not only the energy but also of the particles. This feature opens the possibility for colliding fully polarized electron and positron beams.
