Kelly, A W; Larsen, C J

A klystron is described comprising: an electron beam; a cavity bounded by a set of walls, two opposite walls of the set of walls each having an aperture aligned with each other to allow the beam to enter and exit the cavity; one of the walls parallel to the beam comprising a reversibly deformable diaphragm, and a different one of the walls parallel to the beam having a partially penetrating hole to reduce the thickness of the different wall at the bottom of the hole for the admission of a plunger into the hole to permanently deform the wall at the bottom of the hole to reduce the volume of the cavity and hence the frequency of the klystron is altered to provide fixed tuning, the deformable diaphragm reversibly deforming the wall of the cavity of which it forms a part to reversibly tune the klystron about its fixed tuned frequency.
