MOPPR088	Cavity BPM for 1300 MHz Cryomodules	993
	N. Barov, D.J. Newsham, D. Wu Far-Tech, Inc., San Diego, California, USA
	Funding: Work supported by DOE grant DE-SC00004498 A cavity BPM for 1300 MHz cryomodules is under development by FAR-TECH, Inc. The BPM is capacitively loaded to fit in a small area, and uses a novel coupling scheme which further cuts down space requirements. We discuss status of the fabrication, and eventual plan to test the diagnostic at the ANL Wakefield Accelerator facility.

THPPC044	Development of the Dual Slot Resonance Linac	3383
	N. Barov, X. Chang, R.H. Miller, D.J. Newsham Far-Tech, Inc., San Diego, California, USA
	Funding: Work supported by DOE Grant DE-FG02-08ER85034 We report the status of the Dual Slot Resonance (DSR) linac under development by FAR-TECH. In this linac type, cell-to-cell coupling is provided by a pair of close-coupled resonant slots, resulting in very strong coupling vs. a typical side-coupled linac design, as well as a much more compact radial space requirement. We discuss the status of the structure fabrication, the RF distribution system, and installation and testing at the UCLA Pegasus facility.

THPPC045	Rapidly Tunable RF Cavity for Accelerators	3386
	D.J. Newsham, N. Barov Far-Tech, Inc., San Diego, California, USA
	Funding: Work supported by the DOE-SBIR program, High Energy Physics Department. The performance and range efficient use of rapidly cycling accelerators would be improved with the fast frequency tuning and associated variable phase change provided by a tunable rf cavity. The progress in developing a cavity that can be tuned by as much as 10 percent in frequency in less than 100 nanoseconds is presented.

THPPC073	Development of the Energy-Efficient Solid State RF Power Source for the Jefferson Laboratory CEBAF Linac	3455
	X. Chang, N. Barov, D.J. Newsham, D. Wu Far-Tech, Inc., San Diego, California, USA
	Funding: Work supported by DOE Office of Nuclear Physics, DOE-SBIR #DE-SC0002529 We present the current status of FAR-TECH's Solid State RF Power Source for the Jefferson Laboratory CEBAF Linac. This power source design features up to 8 kW CW RF output power, GaN amplifier stages with high efficiency (>60%), and a compact design to fit existing rack space and cooling requirements at the installation site. We have finished most of the designs and have performed successfully the most critical tests of this project, the 4 to 1 combiner test and the cooling test. FAR-TECH’s solid state amplifier design has high efficiency, a wide range of design frequency (DC-3GHz), and long lifetime, which provides a good RF power source.
