The linear induction accelerator, RADLAC II, is being upgraded to produce a 20-MeV, 40-kA annular beam. Previously, the accelerator produced a 15-MeV, 15-kA beam. Improvements in the pulsed power, injector design, and magnetic field have resulted in a faster rising, flat-topped voltage pulse. The first experiments used only the injector and produced a 5.3-MeV, 47-kA high quality annular beam that was transported in a 20-kG magnetic guide field to the location of the first 2.5-MV accelerating gap. The beam is now being transported and accelerated through two of the six accelerating gaps. The accelerating gaps are of a unique design that minimizes changes in the radial electric field to reduce the amplitude of radial oscillations. The quality of the accelerated beam will be measured through two gaps before adding the remainder of the accelerator. The upgraded beam will allow high current conditioning, lead pulse stability, and current scaling experiments to be completed. 8 refs., 3 figs.
