摘要：本发明公开了一种基于两段矩形光栅的史密斯‑帕赛尔电磁辐射源，包括产生矩形带状电子注的电子枪、大尺寸平板金属矩形光栅、小尺寸平板金属矩形光栅和收集极；电子枪与收集极相对应，大尺寸平板金属矩形光栅和小尺寸平板金属矩形光栅依次放置在电子枪于收集极之间，大尺寸平板金属矩形光栅和小尺寸平板金属矩形光栅的上表面到所述矩形带状电子注的距离相等；电子枪产生匀速的矩形带状电子注依次地掠过所述大尺寸平板金属矩形光栅和小尺寸平板金属矩形光栅的上表面，最后进入收集极。与传统Smith‑Purcell自由电子激光相比，可以使Smith‑Purcell自由电子激光工作在更高次谐波上，辐射频率提高2到3倍。

摘要： A linear beam device comprises a cathode and an anode spaced therefrom, with the anode and cathode being operable to form and accelerate an electron beam. An RF interaction region having a drift tube is arranged relative to the anode to permit the electron beam to pass therethrough. A multi-stage depressed collector of the linear beam device has a plurality of collector electrodes successively arranged to collect spent electrons of the electron beam after passing through the RF interaction region. Each one of the plurality of collector electrodes has a distinct voltage level applied thereto defining a decelerating electric field within the collector. At least one of the plurality of collector electrodes further comprises a collecting surface having a shape that is normal to a coincident trajectory of the spent electrons, whereby a substantial portion of the collecting surface is covered with a plurality of narrow grooves. In an embodiment of the invention, the grooved collector electrode further comprises the final electrode of the collector. The final electrode has a surface that is substantially spherical, and the plurality of grooves may be arranged in a concentric pattern of circles on the electrode surface. The plurality of grooves may be formed to a depth that is approximately twice a corresponding width. A region adjacent to an opening of each of the plurality of grooves comprises electric fields defining a convergent lens, thereby focusing the spent electrons into the plurality of grooves.

摘要： A collector for collecting an electron beam in a traveling wave tube is disclosed. The collector has an input end for receiving the electron beam from the traveling wave tube. The collector also has a plurality of stages biased at given voltages and arranged along a common collector axis and positioned at a different axial position with respect to the input end. A stage is biased more negatively with a voltage than a successive stage positioned axially farther from the input end to generate an electrostatic focusing lens for focusing the electron beam toward successive stages thereby increasing the collection efficiency of the collector.

摘要： A traveling wave tube having an electron gun and a collector assembly is provided. The assemblies include a sleeve placed around an isolator. The sleeve is either heat shrunk or heat deformed around the isolator. Heat shrinking is performed when the sleeve radius is initially larger than the isolator radius. During heat shrinking, the sleeve is heated to cause the sleeve radius to increase and be larger than the isolator radius. The sleeve is then placed around the isolator and cooled causing the sleeve to contract upon the isolator. Heat deformation is performed when the sleeve radius is initially smaller than the isolator radius. During heat deformation, the isolator is inserted into the sleeve. The isolator and the sleeve are then heated so that the sleeve expands to a constrained amount of expansion and then deforms. The sleeve and the isolator are then cooled causing the sleeve to contract upon the isolator.

摘要： An electron beam device comprises a cold cathode 1, modulation means 2 and an anode 3. The components of the device have a longitudinal configuration and enable an electron beam produced by the cathode 1 to be transversely modulated with a microwave signal transmitted along the modulator waveguide structure 2. The modulated output may be propagated along the elongate anode 3 or may be arranged to propagate through the anode substrate 5 and interface directly with an antenna or other circuit element.
