Abstract:
For the funded BERLinPro project, a 100 mACW-driven SRF energy recovery linac (ERL), a SRF photoinjector cavity has to be developed which delivers a small emittance, 1 mm*mr @ 77 pC, high brightness beam while accelerating a high average current within given high power limitations. To achieve these goals the injector is being developed in a three stage approach. In the current design step a cavity shape was developed which fulfills the beam dynamics requirements, implements a high quantum efficiency (QE) normal conducting photocathode with the HZDR choke and insert design and allows for beam studies at currents up to 4 mA. This paper will describe the RF design process, higher order mode studies and the final layout for the cavity production at JLab.
