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...
The authors proposed a photonic-crystal diode resonator capable of applying both DC-bias field and RF field at the same time, that enables the electron flow continuously to the anode regardless of the RF phase and amplitude as long as the modulation depth, the ratio of maximum RF voltage amplitude to DC-bias, is less than one. The proposed scheme employs a novel diode resonator consisting of two metal...
We analyzed a compact lens by using a modified analytical theory and three-dimensional particle-in-cell simulations. In a compact lens, in which the thin lens and paraxial trajectory approximations are not acceptable, an inhomogeneous electric field can be extended to the entire region of the object and the image spaces. Computer simulations of the current density and the electron beam temperature,...
