Methods of electrode designation for electron optics system of electron beam tubes 電子束管電子光學(xué)系統(tǒng)電極命名方法
Main works are as follows : 1 . to design electron guns with plane cathode according to high current electron optics theory 主要工作如下: 1 .根據(jù)強(qiáng)流電子光學(xué)理論,在填充等離子體條件下,設(shè)計(jì)平面陰極電子槍。
The main works of the dissertation are listed as following : fist , know the theorical basis and software use of egun , magic . represent the theory and calculation method of electron optics 本文主要工作如下:掌握egun 、 pic粒子模擬程序兩種軟件設(shè)計(jì)電子槍的理論基礎(chǔ),熟悉軟件使用,闡述電子光學(xué)系統(tǒng)的基礎(chǔ)理論與計(jì)算方法。
The methods that will be discussed are based on concepts derived from various fields , namely electron optics , the interaction of electrons with crystals , elasticity theory , crystal defect theory and crystallography 我們要討論的途徑是以源自多種領(lǐng)域的觀念為基礎(chǔ),也就是電子眼,電子和晶體之間的干擾,彈性理論,晶體缺陷理論和結(jié)晶學(xué)。
However , the manufacture process of twt is so complicated that many kinds of subject , such as electron optics , magnetics , cathode electronics , microwave electronics , electronmagnetic fields theory , material science , mechanics and calorifics are involved in 行波管的研制涉及到電子光學(xué)、磁學(xué)、陰極電子學(xué)、微波電子學(xué)、電磁場理論、材料學(xué)、機(jī)械與熱分析諸多學(xué)科,工藝過程十分復(fù)雜。
Electron optics is a mathematical framework for the calculation of particle paths along given electrostatic or magnetostatic fields. The term optics is used because a charged particle beam can be manipulated using magnetic lenses in a similar fashion to the manipulation of a light beam with optical lenses.
