Abstract:
A radio-frequency (rf) coupling loop for interfacing the resonant cavity of a resonance accelerator with a power transmission line, the coupling loop comprising:a support body mountable within a wall of the resonant cavity of the resonance accelerator; a pair of elongated metallic rods wherein each rod has two opposite end portions and the rods are supported by the support body in parallel relation with and insulated from one another so that when the support body is mounted within the wall of the resonant cavity, one end portion of each rod extends into the resonant cavity, one of the rods being connectable to the central line of the power transmission line for conducting power therefrom, and the other of the rods being electrically connectable to the support body; and electrically-conductive clamping means clampable about the pair of rods so that the clamping means extends between the two end portions of the rods which extend into the resonant cavity and which are adjustable in position along the length of the extending rod end portions to thereby adjust the amount of rf power which is reflected from the coupling loop to the power transmission line.
