论文摘要
CEPC是拟议的高光度Higgs/Z工厂，有可能在360GEV的质量中心能量中升级到顶级工厂。我们对CEPC的圆周进行了优化研究。我们计算了即时发光度，不同圆周的构造和操作成本。关于每个粒子的总成本和平均成本，我们得出结论，CEPC HIGGS操作的最佳周长为80 km。考虑到Z POL的操作，CEPC的潜在高能升级（顶级工厂），最佳周长增加到100 km。 CEPC（SPPC）的漫长质子质子升级也有利于更大的周长，我们得出结论，100 km是该设施的全球优化圆周。
The CEPC is a proposed high luminosity Higgs/Z factory, with the potential to be upgraded to top factory at center-of-mass energy of 360GeV. We perform an optimization study on the circumference of CEPC. We calculate the instant luminosity, the construction and operation cost for different circumferences. With respect to the total cost and average cost per particle, we conclude that the optimal circumference for the CEPC Higgs operation is 80 km. Taking into account of the Z pole operation, the potential high-energy upgrade of CEPC (top factory), the optimal circumference increased to 100 km. The long future proton-proton upgrade of CEPC (SPPC) also favors a larger circumference, and we conclude that 100 km is the global optimized circumference for this facility.
