	Funding: This work was supported by the U.S. Department of Energy, Office of Nuclear Physics, under SBIR grant DE-SC0019719. RadiaBeam is developing an RF beam sweeper for puri-fying in-flight produced rare isotope beams at the ATLAS facility of Argonne National Laboratory. The device will operate in two frequency regimes ’ 6 MHz and 12 MHz ’ each providing a 150 kV deflecting voltage, which dou-bles the capabilities of the existing ATLAS sweeper. In this paper, we present the design of a high-voltage RF sweeper and discuss the electromagnetic, beam dynamics, and solid-state power source for this device.

THPOPA09	High Stability Klystron Modulator for Commercial Accelerator Application	klystron, controls, power-supply, operation	762
	M.K. Kempkes, M. Benjnane, C. Chipman, M.P.J. Gaudreau, A. Heindel, Z. Ruan, R.E. Simpson, H. von Kelsch Diversified Technologies, Inc., Bedford, Massachusetts, USA
	Diversified Technologies, Inc. (DTI) designed and developed a high stability modulator system for a commercial linear accelerator application. The DTI modulator delivers significant advantages in klystron performance through highly reliable functionality as well as flicker- and droop-free operation from 50-500 microseconds up to 400 Hz (duty limited). The main assemblies on the DTI system consist of a controls rack, high voltage power supply (HVPS), modulator, and cooling manifolds for the modulator, high voltage power supply and klystron tube. Two HVPS (upgradeable to four) provide stable and accurate DC voltage which is used to drive a CPI VKP-8352C UHF-band pulsed klystron for the linear accelerator. A solid state series switch, based on DTI’s patented design, provides both pulse control and arc protection to the klystron. Operating with four HVPS, the DTI modulator is able to operate at a maximum average power of ~750 kW at 10⁵ kV, 47 A nominal. At the end of the initial contract, DTI provided two systems and a total of four HVPS (two of which are used with each system).
