Title: Tuning arrangements for resonators of electron velocity modulation tubes
IPC: H01J23/207
Filed: 1957-11-15
Abstract: 862,432. Velocity modulated tubes. STANDARD TELEPHONES & CABLES Ltd. (International Standard Electric Corporation). Nov. 15, 1957, No. 35643/57. Class 39(1). In a velocity modulation tube a resonator comprises a pair of parallel end walls 10, 11, Fig. 4, apertured for beam passage and having tubular members 12 with an interaction gap between them, an annular non-contacting tuning piston 16 surrounding one member 12 which is moved coaxially of the electron beam path to change the resonator volume. Non- contacting means that the piston does not contact any part of the resonator walls. Each of the three resonators 1, 2, 3, Figs. 1, 4, 6, is provided with an annular tuning plunger 16 which surrounds one reentrant pole of the resonator and is movable axially by a rod 19, 21, 22. The coupling devices (a coaxial line 6 for input coupling and a flared waveguide section 7 for output coupling) are arranged to be coupled to the respective resonator at a point within the range of movement of the tuning plunger; in this way the coupling impedance is said to remain constant as the side flange 17 of the plunger remains a constant distance from the outer resonator wall. This gap between flange 17 and the outer resonator wall serves in this respect as a low impedance coaxial line impedance transformer, having a minimum change of admittance over the tuning range, for which purpose the length of the tuning plunger flange and the dimensions of the resonator behind the plunger are suitably chosen also acts as a choke to prevent energy escaping back along the input feeder. Each tuner control rod 19, 21, 22 has individual driving means 23, 24, 25, 23 and 24 being spaced apart around a central tubular support, Fig. 2 (not shown) and 25 being axially aligned with 24. The driving means are respectively coupled to three concentric shafts 26, 27, 28 having adjusting knobs 29, 30, 31. The control hubs 29, 30, 31 may be locked together so that they move in unison for gang tuning, while they can be initially unlocked for individual trimmer, tuning adjustment. The plungers have flexible bellows seals 20. The resonator 2 has no external input or output. The output waveguide section has two impedance matching ramps 36, 37 and an insulating window seal 38, and is generally similar to a magnetron output coupler. The beam is focused by a sectionalised coil 8. The spacing between resonators 2 and 3 is an odd number of quarter plasma wavelengths.
