The primary goal of this program was to improve the performance of induction accelerators with particular regards to their being used to drive FELs. The strategy for achieving this end was to first optimize the nonlinear magnetic material used in induction accelerator construction and secondly to optimize the design in terms of cost, size and efficiency. We began this research effort with an in depth study into the properties of various nonlinear magnetic materials e.g. various ferrite composites, Metglas an amorphous tape composed of steel and glass, and more conventional magnetic materials such as 5050 Ni-Fe tapes. An all-solid-state, nonlinear magnetic pulse compressor, denoted SNOMAD-V was constructed for this purpose. As more information was obtained the design was optimized with the aim of producing as short an output pulse as possible. This unique pulse generator was finally proven capable of producing gigawatt pulses as short as 2 nanoseconds in duration with risetimes less than 150 picoseconds at repetition rates as high as 10 kHz.
