Parametric studies with PARMELA to improve SLC performance

The PARMELA particle dynamics code has been used at SLAC to simulate the SLC injector from the electron gun through the first accelerator section. The strength of injector components was set and tuned based on the simulation results. Parametric studies with PARMELA were conducted in which injector components were varied in an incremental fashion to study their effects on beam parameters such as current transmission, capture of the charge in 20/spl deg/ of the S-Band, required for a satisfactory spectrum, and the emittance. We discuss the results of our simulation and its application to optimizing the performance of the injector.<
