ED - V\xF6lker, Jens TI - High Current Performance of Alkali Antimonide Photocathode in LEReC DC Gun J2 - Proc. of ERL2019, Berlin, Germany, 15-20 September 2019 CY - Berlin, Germany T2 - ICFA Advanced Beam Dynamics Workshop on Energy Recovery Linacs T3 - 63 LA - english AB - 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.
