Abstract
Abstract
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 360 GeV. 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.
