摘要： A cold-cathode electron source of both high frequency and high output, a microwave tube using the same, and its manufacturing method are disclosed. An emitter (24) of the cold-cathode electron source has a sharp point so that the aspect ratio R may be 4 or more. As a result, the capacitance between the emitter (24) and a gate electrode (16) is small correspondingly to the distance from the gate electrode (16). Therefore, the cold-cathode electrons can behave in response to a high frequency. The material of the cathode of this cold-cathode electron source is diamond having a high melting point and a high thermal conductivity, not a conventional material such as tungsten or silicon. Even if the density of the current flowing through the emitter (24) is high, the emitter (24) hardly melts, and consequently the cold-cathode electron source can be adapted to high output.

摘要： An object of the present invention is to provide a cold-cathode electron source successfully achieving a high frequency and a high output, a microwave tube using it, and a production method thereof. In a cold-cathode electron source 10 according to the present invention, emitters 24 have a tip portion tapered at an aspect ratio R of not less than 4, and thus the capacitance between the emitters and a gate electrode is decreased by a degree of declination from the gate electrode. For this reason, the cold-cathode electron source 10 is able to support an operation at a high frequency. A cathode material of the cold-cathode electron source 10 is none of the conventional cathode materials such as tungsten and silicon, but is a diamond with a high melting point and a high thermal conductivity. For this reason, the emitters 24 are unlikely to melt even at a high current density of an electric current flowing in the emitters 24, and thus the cold-cathode electron source 10 is able to support an operation at a high output.

摘要： A vacuum electron device (50) for generating signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field produced by a magnet in the RF section of a tube. After the electrons have passed through the active area of the tube, the electrons strike a collector which, preferably, is a multistage depressed collector. The stages of the depressed collector maybe connected to high energy voltage sources of different potentials. A vacuum electron device (50) with a multistage depressed collector is used here for the first time in a ground based satellite or terrestrial communications system.

摘要： A field emission device is made by pre-activating ultra-fine diamond particles before applying them to the device substrate. This initial pre-activation increases manufacturing speed and reduces cost and reduces potential damage to the device substrate from exposure to high temperature hydrogen plasma.

providing particles comprising diamonds;
having said diamonds predominantly comprising diamonds having maximum dimensions in the range of 5-10,000 nm;
exposing said particles to a plasma-containing hydrogen at a temperature in excess of 300°C;
adhering said particles to a substrate having a conductive portion; and
disposing an electrode adjacent said diamond particles.

摘要： An electron gun (10) that suppresses the non-linear space charge forces and phase-dependant focusing forces that are chiefly responsible for the high emittance of conventional electron guns. The gun comprises a resonant microwave cavity (15), a cathode (12) mounted in the cavity wall, and a momentum analyzer system (17). The resonant microwave cavity, when supplied with microwave power, supports an electromagnetic field having a high-gradient electric component directed along an acceleration axis. The cavity is formed with an exit aperture (32) at a location relative to the cathode such that emitted electrons are accelerated along the axis and pass through the exit aperture. The cavity length is chosen to allow the microwave field within the cavity volume to accelerate the electrons to an energy of about 0.5-1.0 MeV prior to the electrons' passing through the aperture. Bunching is provided by the momentum analyzer. An electron emerging from the cavity has an energy determined by the phase of the microwave field at the time of that electron's emission. Those electrons having energies corresponding to the desired inital phase value are permitted to pass through the momentum analyzer, thereby forming a prebunched electron beam for injection into a linear accelerator.

摘要： A high-power switch tube (10) is shown constructed from a plurality of electron guns each having a cathode (12) and an anode (32). Between the cathode and anode is mounted a shadow grid (22) closest to the cathode beyond which is mounted a control grid (26), a screen grid (28), and, in some applications, a suppressor grid (30). Each anode (32) is formed with an anode cavity (34) having an opening (36) that is smaller in dimension than the largest dimension of the cavity, thus forming a Faraday cage collector which prevents secondary emission problems.
