  The Photo Injector Test facility at DESY, Zeuthen site (PITZ) was built to optimize electron sources and to study electron beam characteristics for short wavelength Free-Electron Lasers (FELs). In addition, using a further accelerating ('booster') RF cavity, the so-called emittance compensation mechanism is under investigation at PITZ. Due to the upgrade of the PITZ facility the gap width of the dipole spectrometer downstream the RF gun cavity was too small and had to be modified. A slit was added in front of the spectrometer to improve the momentum resolution. Design considerations are discussed and first measurement results are presented. Furthermore, the bunch length measurements downstream the gun has been adapted to higher energies.
