The Low Energy RHIC Electron Cooling (LEReC) ac-celerator was successfully commissioned at BNL. To satisfy the electron beam quality required for cooling, a high voltage DC photocathode gun was chosen as the electron source. The LEReC DC gun system is based on the Cornell University ERL gun. The gun was successfully commissioned with high-current and produced electron beam quality suitable for cooling. Here we describe operational experience with the LEReC gun, as well as experience gained with conditioning of such guns.

  The Low Energy RHIC Electron Cooler (LEReC), the world’s first electron cooler to employ an RF electron accelerator, has been recently fully commissioned. The LEReC is a high-current, high-brightness accelerator featuring ~100 m of beamline and is designed to operate with 1.6-2.6 MeV electron beams of up to 140 kW beam power. The LEReC requires a dedicated machine protection system (MPS) capable of interlocking electron beam within 40 us and is equipped with multiple levels of protection. In this paper we summarize our experience with designing, building, and operating the LEReC MPS.
