    Session 5: Application Oriented Research: High Average Current

    Cesium telluride (CsTe) photocathodes has been the first hand choice for electron sources by worldwide accelerators, due to its high quantum yield, stable performance at complicated operation environment and long lifetime. In this work we compared the results of in situ x-ray characterization of the traditional sequential and co-evaporation growth of CsTe photocathodes. We were able to achieve...

    Session 5: Application Oriented Research: High Average Current

    The future upgrade at Relativistic Heavy Ion Collider (RHIC) calls for the implementation of electron cooling strategies, where ultra-cold electron beams will be generated by photoinjectors. To meet this requirement, the photocathode in the injector is required to deliver a high average current of 50 mA. Bialkali cathodes can deliver the required current, however owing to their short lifetime,...
