Tracking through undulator structures

J. Bahrdt, G. Wüstefeld, Symplectic tracking and compensation of dynamic field integrals in complex undulator structures, Physical Review Special Topics, Accelerators and Beams, 14, 040703 (2011)


The tracking scheme as described in this paper is based on analytic generating functions which permit an analytic integration through undulator structures. This scheme is at least an order of magnitude faster than numeric integration. The method is implemented in the tracking code ELEGANT which was developed at the APS:
