Description
Two normal-conducting RF cavities at 49 MHz and 98 MHz have been developed for the bunch-splitting system in the Hadron Storage Ring of the Electron-Ion Collider. Both cavities use compact quarter-wave-resonator structures to satisfy RF, mechanical, and tunnel-integration constraints. Key components, including the fundamental power coupler (FPC), fundamental mode damper (FMD), higher-order-mode (HOM) dampers, mechanical tuners, and pickup couplers, were optimized to meet all design performance requirements. HOM impedances and powers satisfy their limits across the full tuning range. Frequency shifts due to mechanical tolerances can be compensated by trim tuning to adjust the cavity gap. Multipacting studies were carried out using SPARK3D. The designs of both cavities fulfill the performance and interface requirements and are ready to proceed to the procurement phase.
