Lattice design for Low Energy Cooling in EIC HSR-IR2

Insertion Region at two o'clock (IR2) of the Relativistic Heavy Ion Collider will be modified to provide effective cooling for the Electron-Ion Collider (EIC). This paper summarizes the update of the HSR-IR2 lattice design to meet the evolving requirements of the EIC. The geometry has been redesigned to satisfy the yellow-to-yellow configuration. The injection optics is optimized to satisfy the Low Energy Cooling requirements and physical aperture.
