TESLA INJECTOR SIMULATIONS WITH MAFIA

The TESLA Test Facility (TTF) is a test bed for the su-perconducting option of a linear e+/e- collider in the TeV regime. The injector delivers a 20 MeV beam with 1 nC charge per bunch of 1 mm length. It consists of an RF-gun, a superconducting 9-cell Capture Cavity and a chicane bunch compressor. The MAFIA modules TS2 and TS3, the particle in cell programs in 2D and 3D, as well as the mod-ule L, a tracking program, have been used to study the par-ticle dynamics in the TTF, e.g. the emittance growth due to space charge effects in the bunch compressors. Dedicated interfaces for the three different simulation tools allow to study components separately and to hand over beam data from one accelerator section to another or one simulation tool to another, respectively.
