| dc.description.abstract | 本論文前半部主要敘述並探討操作於溫度限制 ( temperature limited ) 條件下的電子光學系統—單陽極 ( single-anode ) 磁控注入電子鎗 ( magnetron injection gun, MIG ) 理論及計算，後半部則以2-l/2維(表示二維的電磁場及三維的粒子運動)電子鎗模擬程式EGUN ( EGUN-An Electron Optics and Gun Design Program, W.B. Herrmannsfeldt, 1989 ) 製作電子鎗的設計範例、並對實驗室目前使用的電子鎗進行數值模擬，最後加入優化後的新電子鎗結構以減低電子束的速度發散。 | zh_TW |
| dc.description.abstract | This thesis is about the design and theoretical simulation of a type of electron-optical system—single-anode magnetron injection guns ( MIGs ), which operate in the temperature limited regime of emission. The first half of this thesis discusses some physical principles applied for MIGs, and for the second half, I’ll present a MIG design example, and simulation results for the MIG being used in NTU applied electrodynamics lab, together with a modified MIG structure based on it to minimize the velocity spread. Theoretical results were obtained by employing a 2-l/2 dimension electron gun code ( EGUN ). | en |
