摘要： A transducer suitable for generating signals in the terahertz region has a resonant cavity (4) with apertures (6) aligned with a cold cathode source (2) being a field emitter array. The resonant cavity (4) consists of an inner cylindrical region (8) and an outer toroid region (9) that includes a slot antenna (11). To achieve signal generation in the terahertz region, the cavity (4) is fabricated using an etched polymeric material.

摘要： 1,195,791. Klystrons. VARIAN ASSOCI. ATES. 16 Jan., 1968 [27 Feb., 1967], No. 2418/68. Headings H1D and H1W. A temperature-compensated iris coupling, for incorporation in a klystron cavity for example, is formed by a first apertured metal member, within the aperture of which is brazed an apertured insert of a different metal of higher thermal expansion coefficient and ductility, the aperture in which defines the iris. The expansion of the first, less ductile, metal, e.g. steel, limits the expansion of the insert, e.g. of copper, the annular width of the insert being chosen, in relation to the thermal expansion coefficients of the two metals, to maintain substantially unchanged iris dimensions at a typical operating temperature, e.g. 100 C. If the insert is in the form of a thin sheet, it is slotted, as shown, from its inner periphery, to avoid buckling. The arrangement is described with reference to circular, rectangular, or oval irises employed in window structures incorporated in a reflex klystron to couple the evacuated cavity to an output waveguide, to an external cavity tuned by a plunger (Fig. 1, not shown), or to a cut-off waveguide tuning arrangement (Fig. 7, not shown). Numerical examples are discussed.

摘要： 922,051. Velocity modulated tubes. VARIAN, ASSOCIATES. Sept. 21, 1961 [Dec. 6, 1960] No. 33924/61. Class 39 (1). A klystron has a massive body portion with two metal inserts 19, 22, Fig. 2, and tuning means for the cavity resonator or resonators which are partly defined by the inserts, and entering at the side, which is in contact with a thin wall portion of the massive body portion, the tuning action causing the resonator gap or gaps to vary in length by bending of one insert. The klystron may be a single resonator reflex klystron or may have two resonators (oscillator with a hole coupling the two cavities, or an amplifier). Massive body 11 is of Cu or of copper plated steel. The resonator or resonators are formed by 11, the two metal inserts, and by a C-shaped member 23, with an intermediate dividing wall if two resonators are present. The reflector is sealed to a ceramic wall member 25. The output waveguide is of rectangular crosssection and has a sealed window 29. Tuning is by a screwed rod or rods entering from the side, and having transverse compressible slots so that it or they can be deformed for locking by a lock-nut or nuts 38, an actuating nut or nuts 36 also being provided. Screwed nut 38 enters screwed sleeve 33. In manufacture, 22 (or both end walls in two resonator forms) is bowed and then the tuner is set and locked by the lock-nut. At least one tuning screw may be of Mo or " Kovar " (Registered Trade Mark) for temperature compensation, e.g. one of these may be fixed and may work in combination with a movable tuner, Fig. 4 (not shown). The gun anode and one of the inserts (19) may be integral.

摘要： 1,011,533. Screw-and-nut gearing. EITELMcCULLOUGH Inc. July 9, 1962 [July 31, 1961], No. 26329/62. Heading F2Q. [Also in Division H1] A tuning mechanism for a resonant cavity in an electron discharge device, e.g. a reflex klystron, comprises a hollow support shell 39, Fig. 2, extending from the device, a tuning shaft 34 movably supported in the hollow support shell for movement upon application of a force falling within a predetermined range, the shell having an internally-threaded portion engaged with an exteriorly threaded portion on the shaft, and means on the hollow support shell to damp vibration of the tuning shaft and maintain within the predetermined range the force required to move the shaft. The tuning shaft is resiliently held, Fig. 1, by a split spring 61 urging metallic members 58 and lubricating member 63 on to its smooth cylindrical surface.
