Description
The Electron-Ion Collider (EIC) uses the local crab crossing scheme to compensate the geometric luminosity loss of the $25 ~\mathrm{mrad}$
crossing angle in the interaction point. Due to space limitations and other optics constraints, the beam optics at the crab cavities in
the Hadron Storage Ring (HSR) is not perfectly matched to fully compensate the crab dispersion.
This paper discusses the possibility of closing the
crab dispersion by a dispersive RF cavity. The formula is derived and the required momentum dispersion at the RF cavity is calculated.
The weak-strong simulation is performed to demonstrate this idea
