Description
The push to create a high luminosity Higgs factory requires the generation and preservation of low emittance beams. In this new low emittance regime, collective effects previously considered negligible must be re-examined, such as intrabeam scattering, which leads to the increase of the sliced energy spread. Omitting intrabeam scattering in our simulations may result in unrealistically high predicted luminosities that do not match reality because of the accumulated emittance growth, hence we must re-examine the importance of intrabeam scattering. The need for low emittance beam preservation also imposes tight tolerances on the alignment and vibration monitoring of beamline elements. Vibrations of the magnets in particular lead to nonlinear deflections of the beam and do not preserve the emittance. Here, the effects of intrabeam scattering and misalignment of beamline elements on the beam emittance are presented for the proposed Cool Copper Collider main linac.
