Description
The Electron-Ion Collider (EIC), a decade-long project at Brookhaven National Laboratory (BNL) funded by the Department of Energy (DOE), aims to design and build a facility for colliding polarized high-energy electron beams with polarized proton and heavy ion beams. The EIC will operate at center-of-mass energies between 20 GeV and 140 GeV and achieve luminosities up to 1034 cm-2s-1. This collaborative effort between BNL and the Thomas Jefferson National Accelerator Facility (Jefferson Lab, JLAB) will use crab cavities to compensate for a 25 mrad crossing angle, thereby maximizing luminosity. These crab cavities require ultra-low noise RF field control to prevent transverse emittance growth. Additionally, the low-level RF (LLRF) system must integrate very low noise performance with high-gain feedback to effectively reduce cavity impedance. We will present preliminary design work on an ultra-low noise LLRF system with high-gain feedback, specifically developed for the EIC crab cavities.
