A detailed knowledge of the parameters of a high-brightness electron beam is of major importance for evaluating the performance of a free electron laser using the beam. Therefore, a full characterization of the beam parameters is required during the commissioning of RF photoinjectors. Contributing to this task, at the Photo Injector Test Facility at DESY in Zeuthen (PITZ) a multi-purpose high energy dispersive arm (HEDA1) for electron energies up to 40 MeV is presently under construction. The dispersive section is designed such that it will combine the functionality of 1) an electron spectrometer, 2) a device for characterization of the longitudinal phase space, and 3) a transverse slice emittance measuring system. The HEDA1 consists of a 180° dipole magnet (C-Bend), followed by a slit, a quadrupole magnet, and a screen station with a read-out for the streak camera. Design considerations and the detailed lay out of the high-energy dispersive section will be presented.
