focusing glass

To select a cylindrical plane cathode ; to design proper focus electrodes in order to control the formation of beam in methods of solving equations , electrobath and simulation aided by computer . to correct effects of anode hole and work out curves of designing guns ; to discuss plasma cathode guns at last 選用圓形平面陰極;設計恰當的聚束極形狀以控制電子束的成形,并使用解析法、電解槽法和數值方法三種方法進行設計;考慮陽孔效應對電子束傳輸的影響,修正陽孔效應,給出電子槍設計曲線;最后討論一下等離子體陰極電子槍。
