An experimental prototype of a pulse magnetron has been developed, having the output power of 2.5 kW at a frequency of 35 GHz with the operation voltage of 6.5 kV. The interaction space of the magnetron has been extended due to the properly selected operation mode - it works at the first negative spatial harmonics. The magnetron's structural scheme includes the main secondary-emission cold cathode...
An analytical estimation has been performed to determine the optimal parameters of pulsed magnetrons, operating at a spatial harmonic at a frequency of 35 GHz and an anode voltage of 6.5 kV in the drift-resonance mode, with the main cathode being the cold secondary-emission one. A 3D simulation experiment on a magnetron with the analytically determined characteristics has been conducted to check its...
100 GHz linear magnetron employing the ten-vane reentrant resonator is investigated by using a two-dimensional particle-in-cell simulation. The dynamics of electron beam, the time variation of electric energy in each vane, and the generated power density are examined when the injected current density is varied. The maximum power density is 180 mW/mm2 at 100 GHz when the current density of 80 A/cm2...
