TEM mode

A compact relativistic magnetron with diffraction output (MDO) of TEM mode has been investigated experimentally by using the EPA-90 high-voltage electron accelerator. The purpose is to verify the diffraction output in low-order mode predicted by numerical simulations. The diagnostic results have indicated that the MDO with all cavity extraction realizes the TEM mode output. When the diode voltage is 480 kV and the axial magnetic field is 0.49 T, the MDO could generate a microwave at a frequency of 2.42 GHz, corresponding to 950-MW output power and 25.8% conversion efficiency. This work paths a way for MDO to realize the radiation with low-order mode.
