ABSTRACT:
A klystron tuning mechanism includes a tuning element support mechanism, a preset section, a driving mechanism, and a pitch changing section. The tuning element support mechanism is arranged in a cavity resonator to be coupled to a tuning element, fixed in the cavity resonator, through bellows, and axially applies a biasing force to the tuning element. The preset section has a plurality of screw members axially positioned in accordance with preset tuning frequencies and selectively movable coaxially with the tuning element, and a preset plate having an internal thread portion meshed with the screw members. The preset section is retractably moved with respect to the tuning element support mechanism. The driving mechanism drives the preset section to retractably move so as to bring a selected one of the screw members into contact with the tuning element support mechanism against the biasing force, thereby positioning the tuning element to a preset position. The pitch changing section changes part of the pitch of the internal thread portion.
