Development of High-Efficiency, High Power Electron Beam Accelerator Technologies

This research investigates the feasibility of improving operational readiness, reliability and availability of high current cryogenic rf linear accelerators using a cryogenic compatible resonant coupling technique to couple all of the accelerator sections together, including any room temperature portion. This technique guarantees a single resonant frequency for the system insuring rapid turn on. The accelerator field amplitudes and phases are locked together without any critical tuning of individual components. This approach also makes the system inherently an ideal rf power combiner and allows operation even if an rf unit is off line.
