Description
Coherent Electron Cooling Proof-of-Principle (CeC PoP) is an experimental accelerator system currently commissioned at Brookhaven National Laboratory (BNL). The purpose is to demonstrate cooling of a single hadron bunch circulating in the relativistic heavy ion collider (RHIC) with co-propagating electron beam. To support CeC operation, FPGA based LLRF Controllers provide system controls, monitoring, RF references and instrumentation timing signals. Synchronization between the Laser source, photocathode electron gun, buncher and SRF accelerator cavity is achieved by broadcasting revolution frequency and resets to each LLRF controller through a high-speed fiber link. CeC is one of the essential techniques being studied for high energy strong hadron cooling, to increase the integrated luminosity goal of the future Electron-Ion Collider (EIC) at BNL.
