摘要： A linear beam device (10) comprises a cathode (12) and an anode (18) spaced therefrom, with the anode (18) and cathode (12) being operable to form and accelerate an electron beam. An RF interaction region (22) having a drift tube (24) is arranged relative to the anode (18) to permit the electron beam to pass therethrough. A multi-stage depressed collector (130) of the linear beam device (10) has a plurality of collector electrodes (132, 134, 136, 138, 142) successively arranged to collect spent electrons of the electron beam after passing through the RF interaction region (22). Each one of the plurality of collector electrodes (132, 134, 136, 138, 142) has a distinct voltage level applied thereto defining a decelerating electric field within the collector (130). At least one of the plurality of collector electrodes (132, 134, 136, 138, 142) further comprises a collecting surface having a shape that is normal to a coincident trajectory of the spent electrons, whereby a substantially portion of the collecting surface is covered with a plurality of narrow grooves (150). In an embodiment of the invention, the grooved collector electrode further comprises the final electrode (142) of the collector (130). The final electrode (142) has a surface that is substantially spherical, and the plurality of grooves (150, 250) may be arranged in a concentric pattern or circles on the electrode surface. The plurality of grooves (150) 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 (150, 170) comprises fields defining a convergent lens, thereby focusing the spent electrons into the plurality of grooves (150, 170).

摘要： A coupled-cavity circuit (10) for a microwave electron tube is shown having one or more cavities (36) whose cross-sections are polygonally shaped, such as rectangles. Located in one or more corners of the polygonally shaped cavities (36) are irises (50) which have a higher resonant frequency. These irises (50) are generally triangularly shaped with rounded corners and one leg of the triangle rounded about the drift tube (38) of the microwave electron tube.

摘要： A linear beam device (10) having a multi-stage depressed collector is provided with means that quickly removes the total voltage across the collector electrodes (22-32) upon detection of an arc between the collector electrodes. The linear beam device (10) comprises a cathode (12) and an anode (16) spaced therefrom that are operable to form and accelerate an electron beam. A collector having a plurality of successive collector electrodes (22-32) is arranged downstream from the anode (16) to collect electrons of the electron beam. At least one power supply (42, 52, 62, 72, 82) is coupled to the collector and provides a plurality of distinct voltage levels to respective ones of the collector electrodes (22-32). The power supply (42, 52, 62, 72, 82) comprises a plurality of serially coupled filter capacitors (46, 56, 66, 76, 86), with each one of the filter capacitors (46, 56, 66, 76, 86) being charged to a respective difference (V-V5) between adjacent ones of the distinct voltage levels. A crowbar circuit (40) or other means is coupled across the plurality of filter capacitors (46, 56, 66, 76, 86). The crowbar circuit (40) or the other means reduces the total voltage across the plurality of filter capacitors (46, 56, 66, 76, 86) to zero upon detection of an arc between any two of the collector electrodes (22-32). According to an embodiment of the invention, the power supply further comprises a plurality of diodes (48, 58, 68, 78, 88) respectively coupled across the plurality of serially coupled filter capacitors (46, 56, 66, 76, 86). The diodes (48, 58, 68, 78, 88) prevent reversal of voltage of a corresponding one of the filter capacitors (46, 56, 66, 76, 86) upon operation of the crowbar circuit (40) or other means.

摘要： A low-power wide-bandwidth klystron (10) comprises a cathode (12) having an electron emitting surface (14) capable of emitting an electron beam (22) and a collector spaced from said cathode (12) and designed to collect the electron beam (22) emitted from the cathode (12). An anode (24) is disposed between the cathode (12) and the collector in order to channel the electron beam (22) into a series of drift tubes (38, 44, 46, 48, 52) that define the electron beam (22) path between the anode (24) and the collector. The drift tubes (38, 44, 46, 48, 52) define gaps in which the input cavity (32) and output cavity (40) interact with the electron beam (22). The input cavity (32) velocity modulates the electron beam (22) by way of a radio frequency input signal and the output cavity (40) extracts the amplified radio frequency signal from the electron beam (22). The drift tubes (38, 44, 46, 48, 52) may define additional gaps (35, 37) between the input cavity (32) and output cavity (40) for intermediate cavities (42, 43) that would provide additional amplification. A voltage potential, positive with respect to the cathode (12) voltage potential, is applied to the anode (24) in order to draw the electron beam (22) from the emitting surface (14) of the cathode (12) and into the drift tubes (38, 44, 46, 48, 52). The anode (24) voltage potential is much larger than required for the desired output power. The output cavity (40) is overloaded by providing it with a load conductance that is at least twice that required for optimal klystron power output. A voltage potential, positive with respect to the cathode (12) voltage potential, is applied to the collector, but the voltage potential difference between the cathode (12) and the collector may be at most one half of a corresponding voltage potential difference between the cathode (12) and the anode (24).

摘要： There is provided a high performance extended interaction output circuit (EIOC) (10) having two cavities (12 and 14).
