Short-pulse accelerator technology developed during the early 1960's t
hrough the late 1980's is being extended to high average power systems
capable of use in industrial and environmental applications. Processe
s requiring high dose levels and/or high volume throughput will requir
e systems with beam power levels from several hundreds of kilowatts to
megawatts. Beam accelerating potentials can range from less than 1 Me
V to as much as 10 MeV depending on the type of beam, depth of penetra
tion required, and the density of the product being treated. This pape
r addresses the present status of a family of high average power syste
ms, with output beam power levels up to 200 kW, now in operation that
use saturable core switches to achieve output pulse widths of 50 to 80
nanoseconds. Inductive adders and field emission cathodes are used to
generate beams of electrons or x-rays at up to 2.5 MeV over areas of
1000 cm(2). Similar high average power technology is being used at les
s than or equal to 1 MeV to drive repetitive ion beam sources for trea
tment of material surfaces over 100's of cm(2).
