Modeling a gyrotron cavity using a 3D CFDTD PIC method
Modeling a gyrotron cavity in 3D and time-domain is very challenging due to the open-end features of cavity structure and higher-order mode excitation employed to achieve high efficiency. In this work, a conformal finite-difference time-domain (CFDTD) method is proposed to simulate a gyrotron cavity and a particle-in-cell (PIC) algorithm is used to describe a gyro electron beam. Our preliminary result shows that the 3D CFDTD PIC method could provide an alternative modeling tool for gyrotron research and design.
