Abstract :
The TESLA linear collider incorporates an X-ray SASE FEL which demands challenging electron beam parameters (typically transverse emittance of 1.6 mm-mrd and peak current of 5 kA). For a realistic electron beam distribution at the entrance of the undulator, tracking has to be done from the cathode through the whole accelerator. Non-Gaussian beam profiles have to be taken into account as well as nonlinear effects such as space-charge, coherent synchrotron radiation field and wake fields. We have done this with several codes: Astra, for the low energy part (<100 MeV), TraFiC4 for the bunch compressor chicanes where CSR influences the particle trajectories and the code Elegant for the 6D tracking with wake fields in the linacs and transport lines. The so-generated electron phase space density at the undulator entrance can then passed to SASE FEL simulation codes. Results of this integrated modeling is discussed
