TI - Layout of the 12 O’clock Collimation Straight Section for the EIC Hadron Storage Ring J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - The design of the Electron-Ion Collider (EIC) Hadron Storage Ring (HSR) calls for using parts of both of the Relativistic Heavy Ion Collider (RHIC) Blue and Yellow beamlines. With the HSR having to circulate low (41 GeV) and high (100+ GeV) energy hadron beams while matching the time of flight in the Electron Storage Ring (ESR), it becomes necessary for the ring lattice to switch from an outer arc to an inner arc in order to accommodate for the change in circumference. To do so, a switchyard is planned for installation in the HSR straight section at 12 o’clock with the other switchyard being placed in the straight section immediately downstream, 10 o’clock. The 12 o’clock straight section is simultaneously dedicated to the EIC 2-stage collimation system. The following reviews the layout constraints in the12 o’clock straight section that come with installing such a switchyard, along with the implications on the linear optics for that straight section at all HSR rigidities. The space allocation, twiss parameters and the mechanical requirements of the HSR betatron collimators that will be installed in this section are also discussed.
