	This presentation will provide a status report on the 2kA, 17MeV, 2-microsecond Dual-Axis Radiographic Hydrotest electron beam accelerator at Los Alamos National Laboratory, and will cover results from the cell refurbishment effort, commissioning experiments on beam transport and stability through the accelerator, and experiments exercising the beam chopper.

	The DARHT-II accelerator will produce a 2-kA, 17-MeV beam in a 1600-ns pulse when completed this summer. After exiting the accelerator, the long pulse will be sliced into four short pulses by a kicker and quadrupole septum and then transported for several meters to a tantalum target for conversion to bremsstrahlung for radiography. In order to provide early tests of the kicker, septum, transport, and multi-pulse converter target we assembled a short accelerator from the first available refurbished cells, which are now capable of operating of operating at over 200 kV. This scaled accelerator was operated at ~ 8 Mev and ~1 kA, which provides a beam with approximately the same nu/gamma as the final 17-MeV, 2-kA beam, and therefore the same beam dynamics in the downstream transport. In this presentation we will show the results of beam measurements made during the commissioning of this scaled accelerator.
