An ICEPIC Convergence Study Using a Relativistic Magnetron
Abstract
The relativistic magnetron under development at AFRL/DEH is designed and improved by simulation before its actual construction. Construction and testing reveals that the simulation performs very well for many parameters but fails to predict the correct input impedance. Questions are also raised about the cell size in the simulations. Thus, simulations are performed on three different magnetron configurations each at three different grid resolutions to study the numerical convergence of the simulations. It is found that the magnetron must be centered on the computational grid for convergence. Conclusions are drawn regarding the cell size needed to simulate the device.
