Skip to Main Content Anisotropy in Ic(B) characteristic of
Bi(2223)/Ag tapes results in a considerable decrease in magnet
critical current, if the magnet winding is only made with the
multifilamentary tape prepared by a standard powder-in-tube
(PIT) technique. In case of cylindrical windings, the turns in
pancake coils, which are located at the magnet ends, have lower
critical currents than those in the other parts of the winding.
In order to eliminate this undesired effect, an intensive effort
is exerted to develop the tapes which have the filaments with
the c-axis oriented in some other direction than the
perpendicular one to the broad tape face of the tape is. In this
work we present the results of calculations of critical currents
of individual turns if such tapes, prepared by a novel tape-in-
rectangular tube (TIRT) technique, are utilized in different
parts of the winding. The analysis shows that the magnet design
has always to be carried out with respect to both the magnetic
field distribution in the wi
