Description

At the Photo Injector Test Facility at DESY in Zeuthen (PITZ) photoelectron guns are conditioned and optimized for free-electron laser (FEL) facilities. In order to achieve a high lasing performance an electron beam with low transverse emittance and high current is required. Measurements of the slice emittance are necessary to determine both properties. At PITZ, transverse emittance measurements are carried out with a single-slit scan due to the strong space charge forces at the low momentum of 20 MeV/$c$. Utilizing a transversely deflecting structure (TDS) toghether with quadrupole magnets allows for slice emittance measurements. The poster shows the measurement setup at PITZ, together with methods to calibrate the beam transport and first measurement results.
