cathode of electron gun

基本解釋

The main construction and key technique of long pulse length hollow cathode plasma electron gun are presented.
給出長脈沖空心陰極等離子體電子槍結構與關鍵技術。
The construction and measurement system of fiber-optic sensor for monitoring the distance between cathode and first grid during assembly of electron gun are described.
本文描述了用于裝配電子槍時控制陰極與第一柵極間距的光纖傳感器的結構及其測量系統(tǒng)。
So, our main work is to obtain a satisfactory electron beam with diameter about micrometers by means of choosing a suitable LaBe cathode electron-gun system and a suitable focusing system.
電子束打靶產生X射線已經是很成熟的理論，因此，本論文的理論研究重點是選擇合適結構的電子源系統(tǒng)與合適結構的聚焦系統(tǒng)并將電子束會聚為微米級的細小束斑。
