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.

In a radiofrequency wave generating apparatus including a metallic radiofrequency wave cavity which is excited in one or more of its modes of resonance in the cavity around a central axis of the cavity including moveable plate means in the cavity mounted perpendicular to the central axis in the cavity and moveable along the central axis, moveable probe means connected to and extending inside the cavity for coupling the radiofrequency wave to the cavity and control means for moving the probe means and plate means in order to select and control the mode of the radiofrequency wave in the cavity the improvement in the control means for positioning the probe means and the plate means in the cavity which comprises: (a) support means mounted on the apparatus adjacent an opening in the cavity and extending away from the apparatus so as to define a path into and out of the opening; (b) sliding means moveably mounting the probe means and mounted on the support means so as to linearly move the probe means along the path into and out of the opening in the cavity along a longitudinal axis of the probe means; (c) first micrometer means mounted between the support means and the sliding means so as to measure the position of the probe means in the cavity; (d) guiding means moveably mounting the plate means in the cavity of the apparatus and providing for precise positioning of the plate means along the central axis; (e) second micrometer means mounted between the apparatus and the plate means so as to measure the position of the plate means in the cavity; and (f) motive means for moving the sliding means and guiding means to control the position of the probe means and plate means in the cavity and providing precise movement of the probe means and plate means in the cavity as determined by the first and second micrometer means.
