ABSTRACT:
A tunable microwave cavity permits adjustment of the penetration of a power coupling probe into the main cavity by adjusting a grounded element of the cavity. A pair of conductive tubes are in telescoping relationship and have mutually engaging threads so that a rotation of one tube causes one tube to pass over the other. A first one of the tubes is mounted to the main cavity and around an aperture in the cavity wall. A power coupling connector is mounted with the second tube, and a rotating electrical contactor is disposed between the outer conductor of the connector and the second tube so that the connector does not rotate with the second tube. A power coupling probe affixed to the end of the inner conductor of the connector assumes various penetration depths within the main cavity in response to a rotation of the second tube. The cavity may be used in a light source including a high frequency power source and an electrodeless lamp disposed in the main cavity.
