Magnetron Cavity Design
A common problem in magnetron cavity design is that many normal modes have similar frequencies and operating thresholds as determined by the Hartree cutoff.
A second problem with relativistic magnetrons like the A6 is that they typically have low efficiency, on the order of 30%. Using simulation software like VSimMD can help engineers discover optimal design configurations to prohibit undesired modes and increase efficiency.
Once a promising cavity configuration is found, the operation of the magnetron can be simulated by introducing electron emission at the cathode surface and making a few other adjustments in the graphical user interface.
