Abstract: At the TESLA Test Facility (TTF) linac the required high peak current for FEL operation is achieved by compressing the beam longitudinally in a magnetic chicane. The peak current after the chicane is determined by the residual energy spread of the electron bunch which is produced by anrf photo-injector. By residual energy spread we refer to the energy spread of a temporal slice of the bunch which can not be compensated by any time dependent energy modulation. To determine the energy distribution, an improved optical system has been implemented to image the beam atan OTR-station after a spectrometer dipole. In this paper the results of the beam profile measurements are presented and compared to particle tracking simulations. It is shown that the residual energy spread in the injector on in order of a few keV only, even at bunch charges of 4 nC.
