TRANSVERSE EMITTANCE MEASUREMENTS AT THE PHOTO INJECTOR TEST FACILITY

This contribution summarizes the transverse emittance studies done at the Photo Injector Test Facility at Zeuthen (PITZ) for producing an electron beam that meets the requirements of the VUV-FEL. Systematic measurements of the beam emittance in a wide range of parameters (e.g. bunch charge, rf phase, solenoid fields) will be presented and compared with simulations.
