W＆RBi－2223饼状磁体实验研究

Test of the Bi-2223 Double-Pancake Coil Made by W&R

摘要:

研究了Ｗ＆Ｒ（先绕后烧）工艺中弯曲半径、绝缘材料对银套Ｂｉ－２２２３带材Ｉｃ的影响。用Ｗ＆Ｒ法制备了内径１６ｍｍ、外径８０ｍｍ．高４７ｍｍ四双饼串联组合磁体，４．２Ｋ下Ｉｃ＝５５Ａ．磁体中心磁场Ｂ０＝０．４４Ｔ。

Abstract:

nfluence of curvature radius and insulation on critical current of Bi-2223 silver-clad tapes havebeen investigated.Characteristics of the test magnet assembled with four double-pancake coils madeby W&R are reported.
