The linear induction accelerator, RADLAC II, is being upgraded to produce a 20-MeV, 40-kA annular electron beam with improved beam quality. 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. Simulations show that the beam quality will be maintained through the accelerator. The final accelerator will produce a 20-MeV, 40-kA annular high quality beam with a small perpendicular velocity component, v/sub perpendicular/, with ..beta../sub perpendicular/c < 0.2 c. 11 refs., 5 figs., 1 tab.
