FIELD: physics.SUBSTANCE: invention relates to high-frequency engineering and can be used in making high-frequency radiation generators. in the first version of the generator compared to a hollow-cathode discharge-based high-frequency radiation generator, having a gas-discharge chamber which includes a hollow cathode and an anode insulated from said cathode, a power supply connected to the hollow cathode and the anode of the gas-discharge chamber, a vacuum system linked to the working cavity of the chamber, wherein the electrodes of the chamber are connected in parallel to an electric load, in the disclosed generator the gas-discharge chamber is made such that the anode lies in the cavity of the cathode to form a coaxial waveguide line, wherein electrophysical parameters of the waveguide line are selected such that the gas-discharge chamber forms a resonance line. In particular, the length of the gas-discharge chamber can be a multiple of the quarter wavelength of the generated high-frequency pulse. In the second version of the generator compared to a hollow-cathode discharge-based high-frequency radiation generator, having a gas-discharge chamber which includes a hollow cathode and an anode insulated from said cathode, a power supply connected to the hollow cathode and the anode of the gas-discharge chamber, a vacuum system linked to the working cavity of the chamber, wherein the electrodes of the chamber are connected in parallel to an electric load, in the disclosed generator the gas-discharge chamber is made such that the anode lies in the cavity of the cathode to form a coaxial waveguide line, wherein the wave impedance of the coaxial waveguide line is matched with the wave impedance of the feeder from the gas-discharge chamber to the electric load and with the load resistance.EFFECT: high power of high-frequency energy pulses generated on the electric load of a generator.3 cl, 1 dwg |
