This paper presents the physics design of the DARHT-II downstream system, which consists of a diagnostic beam stop, a fast, high-precision kicker system and the x-ray converter target assembly. The beamline configuration, the transverse resistive wall instability and the ion hose instability modeling are presented. They also discuss elimination of spot size dilution during kicker switching and implementation of the foil-barrier scheme to minimize the backstreaming ion focusing effects. Finally, they present the target converter's configuration, and the simulated DARHT-II x-ray spot sizes and doses. Some experimental results, which support the physics design, are also presented.
