Non-magnetized bunched electron cooling of ion beams during low energy RHIC operation requires electron beam energy in the range of 1.6-2.6 MeV, with an average current up to 45 mA, very small energy spread, and low emittance. A 400 kV DC gun equipped with a photocathode and laser system will provide a source of high-quality electron beams. During DC gun test critical elements of LEReC such as laser beam system, cathode exchange system, cathode QE lifetime, DC gun stability, beam instrumentation, the high-power beam dump system, machine protection system and controls has been tested under near- operational conditions [1]. We present the status, experimental results and experience learned during the LEReC DC gun beam testing.

We are commissioning the accelerator for the Coherent Electron Cooling Proof-of-principle (CeC PoP) Experiment. The 113 MHz superconducting RF gun with Cs2KSb photocathode serves as a source of the electrons. The gun is designed to operate up to 5 nC beam with repetition rate of 78 kHz. In the paper we present status of the gun as well as achieved beam parameters. The photocathode performance (quantum efficieny, lifetime) is also discussed.
