Abstract

The 2.5D finite-difference-element method (FDM) gun and collector modeling code: CHAELOPS, is under-developing at University Electronic Science And Technology of China (UESTC). This developing program is designed to address the shortcomings of current beam optics simulation for vacuum electron devices. The program specifically targets problem classes including magnetic injection gun (MIG) and multi-stage-depressed collector (MSDC) for the gyrotrons. The code includes the structured grid systems for meshing flexibility; the more accurate particle tracking methods and beam emission methods, including models for secondary emission, and more straightforward graphic outputs. The system language is VC++, employing the orient-object (OO) technology.
