摘要
介绍高均匀度的高场超导磁体的一种设计方法。超导磁体的导体材料为NbTi 和 Nb_3Sn。由于在设计中采用了优选法,所以在考虑了磁体的绕制工艺的情况下能够获得极高的磁场均匀度。文中给出了设计例子,磁体的内外径和高度分别为90、221.58和320mm,其中心场强为10.57T,在磁体中心区域直径为10mm 的球体内可得到优于4.0×10^(-7)的磁场均匀度。
A method for designing the high field superconducting magnet with very high homogeneity is presented in this paper. NbTi and Nb3Sn conductors are used for the superconducting magnet. Using the optimum seeking method in the design of the magnet, very high homogeneity is achieved in consideration of the manufacturing technology for the m-agnet.A designing sample is given. The superconducting magnet has an inner diameter of 90 mm,an outer diameter of 221.58 mm and a height of 320mm. The central field is 10.57T. The field homogeneity of better t-han 4×10-7 within the spherical space of 10 mm diameter at the centre of the magnet has been achieved.
