For medium and high field range of ĥe= 0.6~1.6, n takes about 2, and shielding effect is quite favorable, so that error field in the shielded region is merely within 0.1 % of ĥe. For low field range of ĥe<0.5, on the contrary, n grows up rapidly as ĥe decreases. For example, n takes 12.7 when ĥe= 0.1. Current front having such large n cannot shield the interior uniformly, so that error field increases abruptly near the front, reaching to about 2% of ĥe when ĥe= 0.1. Our method can be available for technical applications such as a superconducting tape, because of its sim­plicity and adequate precision. departmental bulletin paper 福岡工業大学 2004-02-10 VoR application/pdf 福岡工業大学研究論集 2 36 193 199 RESEARCH BULLETIN OF FUKUOKA INSTITUTE OF TECHNOLOGY 02876620 https://fit.repo.nii.ac.jp/record/633/files/36(2)-193.pdf http://hdl.handle.net/11478/00001598 https://fit.repo.nii.ac.jp/records/633 jpn
