The Photo Injector Test facility at DESY in Zeuthen (PITZ) conditions and optimises high-brightness electron sources for X-ray free-electron lasers (FELs). Due to a relatively low energy beam at PITZ (∼20 MeV), the main tool to optimize electron source brightness was projected phase space measurement with a slit mask scan technique. Recently, a new procedure to measure the time-resolved phase space, i.e. slice emittance, was systematically commissioned at PITZ, which adds a transverse deflecting cavity to the slit mask scan. The slice emittance setup optimizations, e.g. time resolution and signal-to-noise ratio, and its applications for electron source optimizations will be presented.
