Abstract
Tubular superconducting magnetic shields were prepared from the (Bi,Pb )(2)Sr2Ca2Cu3O10+x superconductor. The single tube of the wall thickne ss of only 1.8 mm traps magnetic flux density of 30 mT at the temperat ure T = 77.3 K and 60 mT at 63.2 K while for the coaxial system of fiv e tubes of the overall thickness 9.6 mm it increases to 70 mT at 77.3 K. The shielding factor as high as 5x10(6) was found for the supercond ucting tube of inner diameter d = 22 mm and length and inner diameter ratio t/d = 4.6.
