%X The Photo Injector Test Facility at DESY in Zeuthen (PITZ) focuses on the development </td><td width="150">
%X  optimization of high-brightness e-beam sources for FELs like the Eu-XFEL. The main scientific program is generation of in-tense e-beams characterized by small transverse emittance from the photo injector, a critical requirementfor modern FELs. At PITZ, a thorough study of factors influencing emittance growth is carried out. Emittance growth due to space charge can be well controlledby precise laser pulse shaping. ASTRA simulations are utilized for the optimization studies to minimize emittance for various laser temporal </td><td width="150">
%X  transverseprofiles. A benchmarking analysis of gaussian and flattop laser profiles is presented. The lasing process in FEL occurs predominantly through highly chargedslices with low emittance, assumed to originate from the longitudinal core of the electron bunch in the photo injector. The transverse emittance of thesesegments is of major importance. Therefore, the optimization of not only the projected emittance but also the slice </td><td width="150">
