Abstract

The A6 Relativistic Magnetron with Diffraction Output (MDO) with two cathode geometries have been investigated. The cathode radius of the magnetron structure has been decreased to make it operate in π-mode. The radiation from the magnetron is extracted axially by tapering onto a conical antenna only those cavities of the anode that correspond to the symmetry of the radiated modes. CST Electromagnetic finite-difference-time domain Particle-In-Cell (PIC) code has been used to simulate the structure. With an input voltage of 240kV, the magnetic field has been varied to maximize the output RF voltage amplitude.
