摘要： A coupled cavity circuit for a microwave electron tube comprises at least two resonant cavities adjacent to each other. An electron beam tunnel passes through the coupled cavity circuit to allow a beam of electrons to pass through and interact with the electromagnetic energy in the cavities. An iris connecting the adjacent cavities allows electromagnetic energy to flow from one cavity to the next. The iris is shaped to cause the iris mode passband to be lower in frequency than the cavity mode passband while still providing broadband frequency response. In addition, the present coupled cavity circuit operates on an electron beam to interact with the third space harmonic of the second passband (the cavity passband) of the electromagnetic signal. Preferably, this interaction occurs on the second passband as this operational design provides output with higher frequencies without decreasing the cavity size. Furthermore, this operational design provides more frequencies with no increase to the iris size. This results in allowing higher power to be provided to the circuit without thermal degradation of the circuit. Also, because the interaction occurs on the third space harmonic of the second passband, the present operational design results in providing flatter frequency responses.

摘要： A structure to eliminate non-fundamental space harmonics in helical traveling wave tubes (10) is disclosed. The helix (18) radius (24a, 24b) and pitch (22a, 22b) are simultaneously varied over a short distance to improve the efficiency and performance of the tube (10). This new geometry, an adverse space harmonics taper (ASHT), renders the fundamental phase velocity invariant to frequency and distance effects, while adversely affecting all other space harmonics. Another aspect of the invention reduces the temperature of the helix (18) and further improves tube efficiency, so that electronic efficiencies approach 30% in a linear performance region.

摘要： The invention concerns a micro-wave tube comprising at least an electron gun (10) for transmitting electrons to an input waveguide (11) through which they pass transversely and wherein an input signal (Pe) to be amplified is to be propagated, injected at an input end (113), said input waveguide (11) being followed by an output waveguide (12) likewise passed through by the electrons and from which is extracted the amplified signal (Pd) at an output end (119). The electrons are directly density-modulated in the input waveguide (11) by the input signal (Pe) and accelerated, when they come out of the input waveguide (11), by the output waveguide (12) brought to a potential higher than that of the input waveguide (11). The invention is applicable to broadband power micro-wave tubes.

摘要： This invention is predicated on applicants' discovery that a highly oriented nanoconductor structure alone does not guarantee efficient field emission. To the contrary, the conventional densely populated, highly oriented structures actually yield relatively poor field emission characteristics. Applicants have determined that the individual nanoconductors in conventional assemblies are so closely spaced that they shield each other from effective field concentration at the ends, thus diminishing the driving force for efficient electron emission.
In accordance with the invention, an improved field emitting nanoconductors assembly (a "low density nanoconductor assembly") comprises an array of nanoconductors which are highly aligned but spaced from each other an average distance of at least 10% of the average height of the nanoconductors and preferably 50% of the average height. In this way, the field strength at the ends will be at least 50% of the maximal field concentration possible. Several ways of making the optimally low density assemblies are described along with several devices employing the assemblies.摘要翻译： 该发明是基于申请人的发现没有单独高度取向的纳米导体结构并不能保证有效的场发射。 相反，传统的人口密集，高度定向的结构实际上产生相对较差的场发射特性。 申请人已经确定开采的确在常规组件中的单独的纳米导体被如此紧密间隔thatthey在端部处从有效场集中屏蔽海誓山盟，从而减少用于有效电子发射的驱动力。 在与本发明改进的现场装配发光纳米导体（一个“低密度纳米导体组件”）雅舞蹈是高度对准，但是在的纳米导体的平均高度的至少10％的平均距离彼此间隔开的纳米导体的阵列包括 优选为50％的平均高度的。 以这种方式，在端部处的电场强度将是最大场集中可能的至少50％。 使OPTI马利低密度组件的几种方法中描述地连同若干设备用人组件。

摘要： A collector (100) for collecting an electron beam (48) in a traveling wave tube (20) is disclosed. The collector (100) includes at least one collector stage (108) provided with two annularly arranged stage segments (116a,b). The stage segments (116a,b) include overlapping end portions (140a,b) to prevent impingement of electrons of the electron beam (48) against an isolator (120) surrounding the collector stage (108). The stage segments (116a,b) facilitate the realization of transverse electric field distributions from one stage segment (116a) to the other stage segment (116b) within the collector (100) by application of selected voltages to the stage segments (116a,b).
