圆形正负电子对撞机(CEPC)指导委员会已将100公里共用超导射频系统的双环构型定义为基线。基于这一新方案，在初步概念设计报告(Pre-CDR)中保持束流功率不变(Pre-CDR)或在保持发光度不变的情况下降低束流功率(19 MW)，将获得更高的发光度(+170%)。CEPC将与W和Z实验兼容。Z的光度设计为1035 cm−2s−1。通过将环扩大到100公里，对希格斯能量接受的要求降低到1.5%。设计了具有蟹形六极杆的弧光末焦系统(FFS)的光学系统，并介绍了一些初步的动态孔径测量结果。
The 100km double ring configuration with shared superconducting RF system has been defined as baseline by the circular electron positron collider (CEPC) steering committee. Based on this new scheme, we will get higher luminosity for Higgs (+170%) keeping the beam power in preliminary conceptual design report (Pre-CDR) or to reduce the beam power (19 MW) while keeping same luminosity. CEPC will be compatible with W and Z experiment. The luminosity for Z is designed at the level of 1035 cm−2s−1. The requirement for the energy acceptance of Higgs has been reduced to 1.5% by enlarging the ring to 100 km. The optics of arc and final focus system (FFS) with crab sextupoles has been designed, and also some primary dynamic aperture (DA) results were introduced.
