Abstract
A tuner including a shaft extendible through an aperture extending completely through a jacket of the tuner. The tuner includes a shaft tensioning and grounding structure and a tuning material holder comprising a cup-shaped structure with a clasping element.
Claims17
A tuner mounted adjacent an RF resonator to be tuned, comprising:
- a tuner shaft comprising an electrically conductive solid rod disposed within a cavity of the RF resonator and having threads and coupled to a holder for a tuning material;
- a jacket disposed adjacent said shaft;
- and
- a shaft tensioning device disposed adjacent said shaft and separate from said jacket, said shaft tensioning device having means for applying a force to said threads to maintain a position of said shaft and also including grounding structure for maintaining electrical grounding from the electrically conductive solid rod of said tuner shaft to said shaft tensioning device.
A tuner for an RF resonator having a housing with an exterior surface, comprising:
- a continuously threaded tuner shaft including an electrically conductive portion extending continuously from the housing exterior surface into a cavity of said RF resonator and threadably engaging both a spring-loaded flange for applying force constantly to said threaded tuner shaft and also a jacket connected to a resonator housing;
- a substantially cup-shaped turning material holder coupled to said tuner shaft and including a clasping device, said tuning material holder disposed within said resonator housing;
- and
- screws coupled to said flange and said resonator housing, thereby preventing radial and rotating displacement of said flange.
A tuner system comprising, a plurality of resonators with each of the resonators having a cavity and with each of said resonators also having an individual tuner, each said individual tuner associated with a separate resonator detunable by said tuner associated therewith thereby enabling separate tuning of each of said separate resonators;
- and
- a respective tuner shaft comprised of an electrically conductive material coupled to a corresponding resonator housing of each said separate resonator with each said respective tuner shaft of electronically conductive material extending into the cavity of the resonator and means respectively coupled to said corresponding tuner shaft for applying a respective force to said corresponding tuner shaft to maintain good electrical grounding of said respective tuner shaft of electrically conductive material to said means for applying a respective force, in each of said separate resonators.
