RESULTS FROM BEAM COMMISSIONG OF AN SRF PLUG-GUN CAVITY PHOTOINJECTOR

Superconducting rf photo-electron injectors (SRF photoinjectors) hold the promise to deliver high brightness, high average current electron beams for future light sources or other applications demanding continuous wave operation of an electron injector. This paper discusses results from beam commissioning of a hybrid SRF photoinjector based on a Pb coated plug and a Nb rf gun cavity for beam energies up to 2.5 MeV at Helmholtz-Zentrum Berlin (HZB). Emittance measurements and transverse phase space characterization with solenoid-scan and slitmask methods will be presented.
