BEAM DYNAMICS ON-LINE SIMULATIONS FOR THE S-DALINAC INJECTOR

V-Code is the first beam dynamics simulation tool based on the Model of Ensembles. It was successfully applied to the TESLA Test Facility (TTF) injector. V-Code has now been modified in order to fit the requirements of S-DALINAC. One of the new features of the present version of V-Code is the model of a bunched beam. To simulate the S-DALINAC chopper system, the tracking code ChopSim has been developed, yielding the initial ensemble parameters for the main V-Code solver. The S-DALINAC layout, including a set of steerers, RFcavities, lenses and quadrupoles has been implemented. Also, a data acquisition procedure compatible with the SDALINAC control system has been elaborated, providing on-line functionality for the beam dynamics simulation. The obtained results underline V-Code's potential of becoming an all-purpose simulation tool for linear accelerators.
