Description

The EIC Hadron Storage Ring (HSR) reuses the RHIC yellow ring with substantial reconfiguration. A major challenge is mitigating beam-induced heating of cryogenic components caused by the shorter hadron bunches and an average beam current three times that of RHIC. In addition, large transverse beam offsets at injection due to snake magnet itself generate asymmetric resistive-wall losses in the snake BPM region. To limit these losses, the HSR snake assembly uses copper-coated stainless-steel beam pipes with an amorphous-carbon coating to suppress secondary electron yield. This paper presents heating and thermal analyses of the snake BPM assembly. Preliminary simulations show adequate thermal margin, and ongoing work is extending the analysis to a full 3D model for more accurate assessment.
