TUP017 FEL simulation electron software plasma 2015 2015-12 A new HPC simulation suite, intended to aid in both the investigation of novel FEL physics and the design of new FEL facilities, is described. The integrated start-to-end suite, currently under development, incorporates both plasma (VSim) and linac (ELEGANT, ASTRA) accelerator codes, and will include the 3D unaveraged FEL code Puffin to probe novel FEL effects.
