A virtual cathode oscillator with an axially extracted te10 or te11 mode has been investigated using the pic code. it can emit microwaves axially through an antenna without mode converter or transition waveguide, making the system more simple and compact. the efficiency of this device can be enhanced by employing premodulation cavity, resonant cavity, feedback mechanism, and virtual cathode formed by two electron beams
本文利用物理分析和粒子模擬的方法研究了軸向提取te10 / te11模虛陰極振蕩器,結果表明通過引入預調制腔、諧振腔、反饋端面、雙電子束陰極等結構,可以實現結構相對緊湊、束波轉換效率較高的軸向提取虛陰極振蕩器。Second, based on the estimation, the fine dbf is performed and the target spectra are filtered. finally, the inverse velocity transformation and reverse weighting are done, and enough batches of signal are united
然後,根據參量估值結果,進行精細的數字波束形成,濾出目標譜線,做速度譜反變換併合並多批數據,得到待處理的方位向信號。At the same time we obtained that the shg conversion efficiency of the flattened gaussian beam is higher than that of the gaussian beam under the same condition ; in section 3, we have computed the theoretical conversion efficiency of the thg on the flattened gaussian beam, where we also have worked out the type - i and type - 11 ( 1 ) thg conversion efficiency curves versus the same effectors, and found the flattened gaussian beams thg conversion efficiency is higher than that of the gaussian beam too ; in the section 4, we have simulated the field distribution of the shg and thg wave on the flattened gaussian beam
在相同條件下,得出了平頂高斯光束的倍頻轉換效率高於高斯光束的倍頻轉換效率;第三章對平頂高斯光束在clbo晶體上的類和類混頻轉換效率與其影響因素的關系進行了數值模擬和計算,並同高斯光束進行比較,同樣得到混頻時,平頂高斯光束的轉換效率高於高斯光束的混頻轉換效率的結論;第四章模擬計算了平頂高斯光束的倍頻、混頻波橫向光場的分佈形式,得到了諧波場仍為均勻平頂高斯光束的結果。A collinear acoustooptic - deflector of pronton - exchanged linbo3 channel wave - guide is studied. the theoretical analysis, structure design and device fabrication of linbo3 pronton - exchanged acoustooptic wave - guided deflector have been finished in this thesis. the width of wave - guide, the width, spacing, effective aperture and width of electrode of interdigital transduces have been theoretically analyzed and designed
本論文研究了一種質子交換linbo3溝道波導共線式聲光偏轉器,其特點是利用了溝道波導的橫向約束,限制了聲波的發散和衍射效應,使得窄孔徑電極結構得以實現,從而增加了功率密度,使總的聲場驅動功率降低。A virtual cathode oscillator with an axially extracted te10 or te11 mode based on the tomachan accelerator in our laboratory is investigated using the pic simulation code. the tomachan accelerator can run with an electron beam of 400kev and 8. 9ka
基於tomachan加速器電子束參數設計的軸向提取te10 / te11模虛陰極振蕩器,不需要改變束-波作用區結構,只需通過更換提取波導,即可實現te10 / te11模式微波的軸向提取。分享友人
