Abstract

INTRODUCTION The dielectric wall accelerator (DWA) is a new accelerator concept particularly suited for short pulse (<50 ns) and high currents (>1 kA). As we previously presented, the pulsed acceleration field is developed by a series of asymmetric Blumleins (i.e., pulse forming lines) incorporated into the insulator structure (Fig. 1) [1,2]. The maximum gradient of this accelerator is defined by the dielectric strength of the wall dielectrics and the maximum surface flashover electric field capability of the interior vacuum interface in the acceleration region. Solid insulator materials can typically meet the 20-30 MV/m requirement; the interface at the vacuum wall typically cannot. High electric fields are possible with properly angled insulators. These insulators, however, are generally unipolar and are not optimum in the simplest configuration of the DWA (i.e., Fig. 1, where the electric field in the dielectric is always applied to the insulators). Thus we select a stra
