	Funding: Supported in part by US Department of Energy Nuclear Physics SBIR Grant DE-SC0022484 Magnetron RF power sources for single cavities can cost much less and operate at much higher efficiency than klystrons, but they do not have the phase and amplitude control, or the lifetime, needed to drive SRF cavities for superconducting particle accelerators. Existing magnetrons that are typically used to study methods of control or lifetime improvements for SRF accelerators are built for much different applications such as kitchen microwave ovens (1kW, 2.45 GHz) or industrial heating (100 kW, 915 MHz). Muons, Inc. is working with Richardson Electronics LLC to develop fast and flexible manufacturing techniques to allow many ideas to be tested for construction variations that enable new phase and amplitude injection locking control methods, longer lifetime, and inexpensive refurbishing resulting in the lowest possible life-cycle costs. A magnetron suitable for 1497 MHz klystron replacements at Jefferson Lab has been designed, constructed, and tested.

THPOPA09	High Stability Klystron Modulator for Commercial Accelerator Application	klystron, controls, high-voltage, 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).
