A Power Enhanced All-Cavity Axial Extraction Relativistic Magnetron with Self-Injected Structure

To enhance the output power of a relativistic magnetron at a fixed operating voltage, we proposed an all-cavity axial extraction relativistic magnetron with self-injecting structure (SI-RM). The particle in cell simulation was carried out to verify the performance of this relativistic magnetron. The results shows that the SI-RM can achieve a peak power of 3.2 GW, under operating conditions of 500kV and 0.32T. The output power of SI-RM increasing over 50%, compared to previous all-cavity axial extracted relativistic magnetron.
