New simulation code for synchrotron radiation based on a real beam orbit

A computer code to simulate synchrotron-radiation power and spatial distributions has been developed based on the method by Abe and Yamamoto [1], where a real beam orbit is obtained by fitting measurements of beam- position monitors (BPMs) with some offset corrections for BPMs and quadrupole-magnet alignments. In this paper, the status and basic performance are presented. This code has been rewritten in Fortran2003 so as to obtain expectable maximal speed-up by parallel computing, aiming at online alarm systems to take precautions against synchrotron-radiation damage, toward higher beam current accelerators.
