ABSTRACT:
An apparatus 10 with gears (22a, 22b, 22c, 25) for adjusting the position of a plate (13) in a cavity (12) and a rack (51) and gear (53) for moving a probe (15) into and out of the cavity is described. The apparatus includes knobs (34, 55) for controlling the movement of the plate and probe. Micrometers (37, 52) measure the precise position of the plate and probe in the cavity. The apparatus allows very precise tuning for selection of a mode of radiofrequency wave in the cavity and fine tuning within the mode.
