Abstract :
FLASH (free electron laser in Hamburg) is a SASE FEL user facility at DESY, Hamburg. It serves also as a pilot project for the European XFEL. Although the slice emittance is a more appropriate parameter to characterize the SASE process, the projected emittance is a good indicator of the electron beam quality which can be measured in an easy and fast way. In this paper we present measurements of the projected emittance along FLASH. We also analyze the effect of the dispersion on transverse electron beam profiles.
