In August, 2004, the international science community formally backed the development of a superconducting linear accelerator named the International Linear Collider (ILC). It is expected that the accelerator will employ klystrons operating in the range of 110-135 kV, 120-166 A, and 1.5 ms pulsewidth. Due to the accelerator's long pulse length and high power, focusing on power supply and energy storage alternatives promises to yield significant reductions in acquisition costs. Diversified Technologies, Inc. (DTI) has developed a high power, solid-state Marx Bank topology, offering an optimal, silicon-efficient technology for the ILC modulators and power supplies. We estimate the Marx topology can deliver equivalent performance and yield acquisition cost savings of 25-50% versus presently proposed alternatives. In this paper DTI will describe the Marx based technology as it is applied to ILC power systems design, and review recent progress in the engineering of the prototype transmitter.

Diversified Technologies, Inc. (DTI), under a SBIR grant from the U. S. Department of Energy, is developing a driver for a kicker strip-line deflector which inserts and extracts charge bunches to and from the electron and positron damping rings of the International Linear Collider. The deflector requires a driver capable of 10 kV, 200 A pulses of 2 ns duration, after-pulse clamping of the deflector voltage to less than one volt within six nanoseconds, and must function at burst rates of 3 to 6 MHz. The driver must also effectively absorb high-order mode signals emerging from the deflector itself. In this paper, DTI will describe a promising approach to the design of the kicker driver involving high voltage DSRDs (Drift Step Recovery Diodes) and high voltage MOSFETs. In addition, our design approach to meeting the challenges posed by the ILC requirements will be discussed.
