A Linac generator program as pre-processor for the simulation code DYNAC

A linac generator program, GENAC, has been developed, capable of generating an accelerating structure through interpolation of SUPERFISH output files. GENAC can handle long and complex accelerating elements, such as asymmetric ones or elements consisting of several accelerating gaps in one go. GENAC is a pre-processor to the beam simulation code DYNAC [1]; both programs are based on the same set of quasi-Liouvillian beam dynamics equations. With the DYNAC code one has the possibility of using multistep space-charge calculations [2],[3],[4] within the accelerating elements of a linac. Therefore, the combination of the linac generator GENAC with the simulation code DYNAC constitutes a powerful tools for the development of new types of accelerators.
