Phase space measurements with tomographic reconstruction at pitz

The major objectives of the Photo-Injector Test Facility at DESY in Zeuthen, PITZ, are research and development of high brightness electron sources suitable to drive FELs like FLASH and the European XFEL. In the 2008/2009 run period the facility has been operated with a new photocathode laser system and a dry-ice cleaned RF gun cavity. Characterization of the transverse phase space of the electron source has been performed in details using a single slit scan technique with a dedicated Emittance Measurement System. In preparation for the forthcoming run, a number of quadrupole magnets have been installed and tomographic reconstruction with data from quadrupole scans with two magnets has been carried out in a semi-parallel manner to the slit scans. This contribution summarizes the experience from the phase-space tomographic reconstruction with nominal beam conditions. Advantages and drawbacks of the measurement procedure and the analysis are discussed. The results are compared to the ones obtained with the slit scans.
