【摘要】:基于自由電子激光(FEL)的太赫茲源具有高功率、高效率、波譜范圍寬且連續(xù)可調(diào)、波束質(zhì)量好等顯著優(yōu)點,目前是獲得最高輸出功率的方法。緊湊型太赫茲源使整體裝置小型化,減少了裝置成本和占用空間,但依然可以提供高功率、高品質(zhì)的太赫茲波束,是一種便利可靠的用戶裝置。由于空間限制,FEL上的磁鐵要盡可能地減小其尺寸,并仍能滿足束流參數(shù)設計要求。本文設計的四極磁鐵磁軛孔徑與有效長度,其中2塊是64mm×100mm,另外3塊是45mm×100mm。這些四極磁鐵的磁場梯度可以達到0.6~1.9T·m-1。采用Poisson和Oprra-3D軟件進行四極磁鐵的二維和三維仿真計算,設計優(yōu)化四極磁鐵的結(jié)構(gòu),并測量了加工完成后的四極磁鐵的磁場。
[Abstract]:The terahertz source based on free electron laser (FEL) has the advantages of high power, high efficiency, wide spectrum range, continuous tunability and good beam quality. At present, it is a method to obtain the highest output power. Terahertz beams are a convenient and reliable user device.Due to space constraints, the magnets on the FEL should be as small as possible and still meet the design requirements of beam parameters.The aperture and effective length of the quadrupole magnet yoke designed in this paper are 64 mm *100 mm in two pieces and 45 mm *100 mm in three pieces. Poisson and Oprra-3D software are used to simulate and calculate the quadrupole magnet in two and three dimensions. The structure of the quadrupole magnet is optimized and the magnetic field of the quadrupole magnet is measured.
