A conceptual design for a 4MV-15MJ pulsed power system to heat inertially confined pellets to fusion temperatures is presented. The PBFA II accelerator is appropriately modified for use in this design. The Marx is rearranged to deliver 8MV to an open-circuit with 15MJ stored energy. Four high power density 40ns pulselines from a PBFA II module are replaced without loss of energy storage by a single 250ns precision pulseline that is capable of 20:1 light ion beam bunching-sufficient to match the power of Supermite. The PBFA II sub-nanosecond laser-triggered gas switch is used to switch the pulseline onto three ceramic insulated vacuum tubes, each with four 20cm × 100cm area, four-stage ion beam acceleration grids. The inherent angular divergence is potentially ≤2 milliradians-far less than that attainable in magnetically insulated diodes. A PBFA II equivalent beam capability of 100TW and 3.5MJ at 4MV is demonstrated using only 18 precision pulselines. Experiments on ORCA I are used to prove that the basic element — the Salisbury low em'ittance beamlet — can be injected into a vacuum propagation region after being programmed for nearly 100% electron neutralization, for almost 20:1 bunching, and for ballistic focusing onto a sub-centimeter radius target 400cm from the source.
