Validation of 3-D Time Domain Particle-in-Cell Simulations for Cold Testing a $W$ -Band Gyrotron Cavity


This paper evaluates the performance and reliability of a commercially available 3-D conformal finite-difference time-domain particle-in-cell (PIC) code, VSim, for cold test simulations of a gyrotron cavity. An interaction cavity for a 95-GHz gyrotron is simulated and optimized using the VSim PIC code to achieve TE6,2 mode excitation. The optimized cavity… (More)
