In the paper, we suggest a proposal that if n sections of the superconducting hollowed cyllinder which has been longitudinally cut are put into n longitudinal field coils for Tokamak apparatus, electric power of longitudinal field coils can be reduced to 2/n by sectional freezing of toroidal field,

本文提出一个设想:即将n个中空超导圆柱体放置于n饼纵场线圈之中,分段冻结环向磁场,则其所需要的电功率将比常规线圈降低到2/n倍。 我们知道超导材料的冻结场可近似地写为。H_(fj)(r,T)=H_(fj)(r,0)[1-(T/T_c)~2。因此选定T=T_1,当轴向场H在大圆环的内壁达到H≥H_(fj)(r,T_1)时,中空体的内边缘达到临界场,则场进入中空区,再使H降到零,中空区就冻结了一个从H_(fj)(r,T_1)的场。然后使这段中空超导段降温到远离T_1的T_2温度,因此在冻结它邻近的另一个中空体时,这个中空体将不受到影响。 由于这样获得环向场所需的功率降低了2/n倍,所以目前已经运转的中等大小装置的电源就能满足动力堆的需要。 由于冻结了磁场为H_(fj)(r,T_1)的超导环段全处在T_2温度,所以当等离子体电流建立后,这些中空超导环还可以和平衡场、反馈场一起更好地平衡、稳定等离子体;超导段与沿大环内向割缝的铜壳组合成一个组合体不仅大大地扩展铜壳稳定、平衡等离子体的作用,而且还可以使铜壳壁减薄。 它与超导磁体相比,虽然所需的电功率高,但它恰可避免了超导磁体材料受到巨大的电磁力引起材料微小...
