Description

High-brightness, megahertz-rate electron sources are a crucial component of future light sources, including the Linac Coherent Light Source II High Energy project, or the high-duty-cycle upgrade of the European X-ray Free-Electron Laser. The Helmholtz-Zentrum Dresden-Rossendorf has employed a superconducting radio-frequency (SRF) gun as one of its CW electron sources for user operation at ELBE since 2010. The SRF gun is used to drive the superradiant THz source TELBE, typically at repetition rates of 50 kHz and bunch charges of 200 pC. To determine the operating envelope of the SRF gun injector, a slit-scan setup was installed in the diagnostics beamline after the SRF gun, enabling characterization of the vertical phase space. In this proceeding, we describe the slit-scan setup at the diagnostics beamline of the SRF gun. Measurements of the vertical emittance at 200 pC bunch charge and beam energies of 3.5 MeV will be presented.
