Abstract :
The authors obtained improved magnetic shielding by superimposing a double-magnetic cylinder over a YBCO (Y-Ba-Cu-O) cylinder. The value of the magnetic shielded field for the superimposed cylinder was 47 times larger than that of the YBCO cylinder. The magnetic shielded field obtained when superimposing a soft iron single-cylinder over a YBCO cylinder was analyzed using the Bean, Wills, and Mager models, with an important criterion being derived for designing an effective shield of the chamber
