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.
VSim, with its intuitive visual interface, can be used to iterate on cavity shape and configuration, then quickly compute the normal modes and their frequencies to produce a magnetron with increased separation between modes.
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.
