Abstract: GINGER [1] is an axisymmetric, polychromatic (r -z -t) FEL simulation code originally developed in the mid-1980's to model the performance of single-pass amplifiers.Over the past 15 years GINGER 's capabilities have been extended to include more complicated configurations such as undulators with drift spaces, dispersive sections, and vacuum chamber wakefield effects; multi-pass oscillators; and multi-stage harmonic cascades.Its coding base has been tuned to permit running effectively on platforms ranging from desktop PC's to massively parallel processors such as the IBM-SP.Recently, we have made significant changes to GINGER by replacing the original predictorcorrector field solver with a new direct implicit algorithm, adding harmonic emission capability, and switching to the HDF5 IO library [2] for output diagnostics.In this paper, we discuss some details regarding these changes and also present simulation results for LCLS SASE emission at λ =0.15 nm and higher harmonics.
