DESIGN AND PERFORMANCE SIMULATION OF THE TTF-FEL II BUNCH COMPRESSION SYSTEM

T. Limberg, F. Stulle

Open publisher page 4 citations

Abstract

We describe the bunch compression scheme for the TESLA Test Facility Free Electron Laser upgrade (TTF-2). The required peak current is 2.5 kA for operating the SASE-FEL within the saturation regime at a wavelength of 6 nm and with an electron beam energy of ∼1 GeV. The beam transverse slice emittance and the final energy spread should be held within the limit of 2.0 mm-mrad and ∼1 MeV respectively. We present a start-to-end simulation of the beam dynamics from the rf-gun up to the undulator entrance.
