C-band high power RF generation and extraction using a dielectric loaded waveguide.
We report on design, fabrication, and beam test of a 7.8 GHz power extractor recently conducted at the Argonne Wakefield Accelerator (AWA) facility. The wakefields are excited using an electron beam travels through a dielectric loaded waveguide, and the generated RF power is then subsequently extracted with a properly designed RF coupler. In the experiment, 30 MW of output power is excited by a 66 nC single electron bunch, and wakefield superposition by a train consisting of four bunches is also demonstrated. Both results agree very well with theoretical predictions. Future tests include more charge transmission for higher RF power, and more bunches in a train for longer RF pulses.
