Accurate large signal analysis of a wideband helix TWT using Beam Wave Interaction Simulator

Using Beam Wave Interaction Simulator (BWIS), one module of Microwave Tube Simulator Suite (MTSS), a wideband helix TWT has been accurately simulated. The slow-wave circuit parameters are calculated by High Frequency Circuit Simulator.

High Frequency Circuit Simulator based on finite integration technology

This paper provides the design and realization of high frequency circuit simulator (HFCS) which is based on the Finite Integration Technology. For vilification, the cold-test characteristics of two actual helical slow wave structures have been calculated and the results were found to be consistent with those of MAFIA simulation with same mesh density.

Impedance calculation of helical slow-wave structure using HFCS-I and MAFIA

Using HFCS-I and MAFIA, the impedance characteristics of a typical helical slow-wave structure (SWS) is studied, in which the Non-Resonant Perturbation (NRP) Method is adopted and the direct calculation from discrete Electromagnetic (EM) fields is performed. The results from HFCS-I and MAFIA are found to be consistent.

The experimental verification of ELECTRON OPTICS DESIGNER

Electron optics designer (EOS) (Tao Huang et al., 2007) is a fully three-dimensional (3D) finite- element (FE) steady- state trajectory code, which is a solver of electrostatic field and trajectory that takes into account secondary electron, space-charge effect and external magnetic field. To validate the code, this paper illustrated two typical experimental verifications of electron gun and collector.
