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。One of effective ways of overcoming space charge effect is to fill plasma in high power wave apparatus, by the neutralization between plasma and space charge, the transfer current is going to be largely enhanced, thereby out - power is going to be largely increased. meantime, due to there are many fluctuating modes in plasma, so it is able to bring a new beam - wave interaction mechanism, by it people can invent some new type high power microwave apparatus
高功率微波裝置中的電流密度很大,空間電荷效應強烈,影響了功率的提高,克服空間電荷效應的有效方法是在高功率微波器件中填充等離子體,由於等離子體對空間電荷的中和作用,傳輸電流會大大提高,從而大幅度提高輸出功率,同時由於等離子體中存在多種波動模式,有可能帶來新的注波互作用機制,發展新型的高功率微波器件。
