Analysis of Beam Dynamics in a Circular Higgs Factory
Cai, Yunhai.
We design a circular Higgs factory with a center-of-mass energy of 240 GeV residing in a 50-km tunnel. Aside from two strong focusing systems and a low-emittance lattice in arcs that are required to achieve a factory luminosity of $1.0\times10^{34}{\rm cm}^{-2}{\rm s}^{-1}$, a large momentum aperture of 2\% is absolutely necessary to mitigate the effect of beamstrahlung and retain an adequate beam lifetime. This turns out to be the most challenging aspect in the design. We comprehensively study ... Show Full Abstract
We design a circular Higgs factory with a center-of-mass energy of 240 GeV residing in a 50-km tunnel. Aside from two strong focusing systems and a low-emittance lattice in arcs that are required to achieve a factory luminosity of $1.0\times10^{34}{\rm cm}^{-2}{\rm s}^{-1}$, a large momentum aperture of 2\% is absolutely necessary to mitigate the effect of beamstrahlung and retain an adequate beam lifetime. This turns out to be the most challenging aspect in the design. We comprehensively study the single-particle dynamics and identity many nonlinear aberrations that limit the performance of the optics.
