The Design And Implementation Of Traveling-Wave Tube Electron Optics System Simulation Software

Nowadays, the Microwave Tube Simulator Suite( MTSS) of University of Electronic Science and Technology of China(UESTC) and the electron tube simulation software TAU of Ukraine are the special codes used for traveling wave tubes( TWTs),also including some general commercial software of the electromagnetic simulation software such as CST and HFSS. At the same time, the Chinese Academy of Sciences Institute of Electronics, the no.12 research institute of China Electronic Technology Group Company, the 772 edfactory and the 776th factory are also developing the electron tubes simulation software modelsor systems with the proprietary intellectual property rights.The TWT electronoptics system(TWT EOS) simulati on software developed by 776th factory can be used to the TWT’s electron gun and magnetic focus system which work at L, S, C, X, Ku and Ka band. It was also played an important role in the simulation of the THz TWT.The TWT electron optics systems imulation software developed by 776th factory is written by the FORTRAN language with an economical and convenient platform, which can fit the demand high pace of product design and development. The software can be used to calculate the Pierce e-gun with or without grid, pole-control lede-gun, complex e-gun with multi-electrode, and the e-gun with field-emitting cathode and so on. The result of the calculation display on the scre en include emitting current, voltage of each electrode, waist of the e-beam, the position of e-beam waist, duty and flow rate of the e-gun, which can help designer easily judge the quality of the parameters of the e-gun.The TWT elec tronoptics system simulati on software combined into TWT_CAD TWT-simulation software, which can easily modify the structures parameters of e-gun.The software has been applied to the duration of manufacturing, R& D and recomputed in the 776th factory, which has made significant effect on design efficiency of the e-gun of TWT and magnetic focusing system design, and remarkable economic results have also been achieved...
