【摘要】：基于自由电子激光(FEL)的太赫兹源具有高功率、高效率、波谱范围宽且连续可调、波束质量好等显著优点,目前是获得最高输出功率的方法。紧凑型太赫兹源使整体装置小型化,减少了装置成本和占用空间,但依然可以提供高功率、高品质的太赫兹波束,是一种便利可靠的用户装置。由于空间限制,FEL上的磁铁要尽可能地减小其尺寸,并仍能满足束流参数设计要求。本文设计的四极磁铁磁轭孔径与有效长度,其中2块是64mm×100mm,另外3块是45mm×100mm。这些四极磁铁的磁场梯度可以达到0.6~1.9T·m-1。采用Poisson和Oprra-3D软件进行四极磁铁的二维和三维仿真计算,设计优化四极磁铁的结构,并测量了加工完成后的四极磁铁的磁场。
[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.
