One type is the iconoscope. it contains three essential parts - - a mosaic, a collector ring and an electron gun
一種是光電攝象管，它有三個基本部件- -嵌鑲光電陽極、集電環和電子槍。 -
In chapter 2, the principles of mdc for twts, refocusing and the influence of the secondary electrons are analyzed. the electron energy entering the collector is analyzed
第二章從分析互作用后電子能量分佈入手，分析多級降壓收集極的工作原理、再聚焦原理和次級電子的影響。 -
To make pic ( particl - in - cell ) simulations. to set up models of guns and magnetic field and simulate them in the vacuum and plasma, respectively. we found that plasma held back part of space charge effects and improved trajectory of electrons. but beam would oscillate and became instable as accretion of plasma density. by simulating again and again, we draw a conclusion magic could n ' t work when plasma density was more by far than beam electron density. at last a four - stage depressed collector was simulated
建立電子槍和聚焦系統模擬模型，分別在真空和填充等離子體條件下進行模擬。發現填充等離子體能補償部分空間電荷效應，改善電子束包絡軌跡，提高電子的流通率，但是隨著等離子體密度的增大，束電子會出現振蕩不穩定性，遺憾的是通過反復多次模擬發現本文所用粒子模擬的代表性軟體magic無法用於模擬等離子體密度遠高於束電子密度的情況。
