Description
The Electron-Ion Collider (EIC) will operate with a 25 mrad crossing angle at the interaction points to enable rapid beam separation, reduce detrimental beam-beam effects, and provide space for forward detectors. This crossing geometry, however, significantly reduces the overlap region of the colliding bunches, resulting in nearly an order of magnitude luminosity loss. To restore effective head-on collisions and achieve maximum luminosity, crab cavities will apply transverse kicks to each bunch, rotating them in the crossing plane. The success of this scheme depends critically on the performance of the Low-Level RF (LLRF) system, which must deliver high-gain, low-noise field control to suppress transverse emittance growth and maintain beam stability. This presentation will describe the LLRF system architecture and control strategy for the EIC crab cavities, including RF noise mitigation, impedance control, crabbing phase closure, and integration planning. The current hardware development status and the roadmap toward full system implementation will also be presented.
