Design and performance of the DARHT second axis induction cells and drivers

The second axis of DARHT, a Dual Axis Radiographic Hydrodynamic Test facility at Los Alamos National Laboratory, is in production with a scheduled completion date of August 2001. This linear induction accelerator, designed by Lawrence Berkeley National Laboratory, consists of 88 induction cells and drivers which provide a total acceleration of 20 MeV to a 2 kA electron beam which has a flat-top pulse width of 2.02 /spl mu/s. Major induction cell components include high flux swing magnetic material (Metglas 2605SC) and a Mycalex insulator. The cell drivers are pulse forming networks (PFNs) which are tuned to provide voltage regulation of /spl plusmn/0.5% during the flat-top. This paper describes the design and performance of the cells and cell drivers.
