Abstract
866,246. Cavity resonators. VARIAN ASSOCIATES. March 26, 1959 [April 24, 1958], No. 10715/59. Class 40(8) A cavity resonator chamber, for use in stabilizing the frequency of an oscillator such as a reflex klystron, has a main wall 11, e.g. of "Invar" (Registered Trade Mark), and a wall 18, for temperature compensation of the chamber, comprising a rim portion 34 made of a material of relatively low coefficient of thermal expansion, e.g. "Invar", secured to the main body 11, and a central portion 33 made of a material of relatively high coefficient of thermal expansion, e.g. steel, the wall 33, 34 including thin annular flexible sections 36, 38 around the junction 40 of the portions 33 and 34 which flexes under temperature change to cause the central portion 33 to move within the chamber. The sections 36 and 38 are secured together along a surface lying on a cone. Adjustment can be made by making a cut 45 in the portion 33 near the section 36, or by shaving the surface 46, Fig. 5. Ribs 21<SP>1</SP> are provided on the wall 18 and the other wall 19. A tuner mechanism for changing the dimensions and hence the resonance frequency of the chamber is mounted in an aperture in the central portion 33 and comprises a circular tuning plate 23, a hollow cylindrical flexible bellows 24 seated at one end to the plate 23 and at the other end to an annular lip 25 on the hollow cylindrical extension 22 of the wall 18, a hollow cylindrical tuner screw 26 threaded into the extension 22, the inner end of the screw contacting the plate 23, a locking screw 27 secured to the plate 23, and a nut 28 on the screw 27 and co-operating with a ledge 31 on the inner surface of the screw 26 for drawing the plate 23 into engagement with the tuner screw 26. The extent of travel of the tuner screw 26 is limited by the lip 25. A pair of coupling holes 12, 13, which may be sealed with dielectric windows, communicate with input and output waveguides 14 and 15 of "Invar" brazed to coupling flanges 16, 17 of steel or brass, the input element being a reflex klystron 20.
