Description
The Photo Injector Test Facility at DESY in Zeuthen (PITZ) optimises electron sources for their use at the free-electron lasers FLASH and European XFEL in Hamburg. Non-linear space charge forces after emission lead to an increase of the transverse (slice) emittance. Photocathode laser pulse shaping allows to alter the space charge forces. This contribution shows a method to measure the slice emittance using a single-slit scan and a transversely deflecting structure, as well as measured slice emittance of three beams, emitted using laser pulses with different shapes.
