Abstract

715,463. Velocity-modulated tubes. SPERRY CORPORATION. March 10, 1950 [March 26, 1949], No. 6097/50. Class 39(1) [Also in Group XL(b)] A klystron comprises a plurality of resonators formed as cylindrical holes in a single block of conductive material, or in the form of cylindrical members traversing a framework of conductive material, and a rectilinear passage for the electron beam is provided to intersect each of the resonators, the axis of this passage being perpendicular to the principal axes of all the resonators. In the three-resonator klystron of Fig. 3, the resonators 7, 8, 9 are formed by bores in the block 1. Posts 3, 4, 5, 6 located in the passage for the electron beam carry grids 18, 19, 20. The grids 18, 19 are formed by a set of single triangular vanes for optimum transmission of beam current. whereas the grids 20 are formed by a set of double triangular vanes 56, Fig. 3A, for optimum coupling. The drift tube defined by post 4, Fig. 5, is longer than the drift tube defined by post 5 for optimum operation. In assembly, clamping screws 55, Fig. 3, hold the posts in position until they are brazed or soldered to the block 1. Recessed bores in the side of the block receive coupling members 14, 15, 16. The resonators are closed at their ends by diaphragms 26, 27, 28, Fig. 5, formed in side plates 24, 25. Outer plates 31, 32 carry differential screw assemblies 33 for flexing the diaphragms and so tuning the resonators. In a modification the plate 32 may carry the coupling members, instead of tuning assemblies. In another embodiment, Fig. 6 (not shown), the resonator bores are not carried right through the block. In the klystron of Fig. 8 the resonators consist of cylindrical members 90, 91, 92 within a framework composed of plates 107, 108, 109, 110. Cooling fluid is circulated in the space between these plates and the resonator members. The plate 108 forms one end closure for the resonators and carries the coupling members 120, 121, 122. The other ends of the resonators are closed by flexible diaphragms which are acted upon for tuning by the screw assemblies 33 carried by an outer plate 118. Provision may be made for gang-tuning the resonators. The multiresonator klystron may be operated as a straight or synchrodyne amplifier.
