In Rossendorf, a new 3*-cell cavity is under preparation and will be installed to the SRF photo injector in April 2014. This cavity is constructed and tested in Jefferson Lab, with the designed final energy up to 7.5 MeV.
The simulation presented in this contribution includes the particle tracking in the new cavity itself with ASTRA, and also the bunch transport in ELBE with elegant. On the cathode, the profile and time structure of the UV laser are utilized to specify the electron bunch parameters. Then a single bunch of electrons are tracked in the cavity field that calculated by Superfish. From the exit of the cavity, we apply the elegant matrix calculations for magnet elements and accelerator modules.
The main purpose of this simulation is to find the optimized parameters of different beam transport tasks. For a more convenient operation among different codes, a Labview program is introduced which executives all codes automatically from settings of parameters to the final results.
