Abstract :
The performance of 14-vanes 5.8GHz strapped magnetron is modeled, including cathode, vane, straps, pole pieces and output antenna using three-dimensional electromagnetic simulation code. The electric field distribution in the cold cavity simulation and the formation of the seven electron spokes confirm the π mode work in the oscillation cavity region. The output frequency 5.787GHz and output power 5.4kW in the hot test simulation is obtained in the uniform magnetic field distribution condition. The magnetron with an efficiency of 60% is operated at the beam voltage 4.5kV, the anode current 2.0A when the external axial magnetic field of 0.235T is applied. The simulation values by Fourier transformation of the voltage signal show a good output frequency spectrum.
