  The bi-alkali antimonide photocathode are chosen as the electron source material for the Low Energy RHIC electron Cooling (LEReC) project at RHIC, BNL based on its requirement for high bunch charge and long-time beam operation. This report presents the design and operation of the cathode deposition and transportation systems for the LEReC photocathodes, the cathode performance under the high current operation in the LEReC DC gun, as well as the characterization of the damaged cathodes from the long-time operation.

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.
