太赫兹FWG-TWT电子光学系统的数值模拟验证
Simulation and verification of the optics system of micro-electronic vacuum FWG-TWT
摘要
Abstract
For 0.22 THz micro-electric vacuum Folded Waveguide Traveling Wave Tube(FWG-TWT) amplifier, the model of whole electronic optics system for experiment is simulated. First of all, electron gun's working mechanism is analyzed and verified by simulation. Then the whole electronic optics system (including electron gun and periodic permanent magnetic focusing structure) is modeled. Combined with actual experimental conditions, the operating parameters and boundary conditions of the whole electronic optics system are set up properly for simulation. The key factors influencing the passing rate of electron beam are analyzed, and the structural parameters and beam parameters of electronic optics system are adjusted to improve electron beam's DC passing rate.关键词
