Abstract

Some high-temperature oxide superconductors (HTSCs) exhibit their best electromagnetic transport property at 4.2 K, which can be applied to produce high magnetic fields. The adiabatic stability of Bi-2212 at 4.2 K is analyzed. A configuration of the composite Bi-2212 conductors which can be used in a high magnetic field magnet is suggested. The stability performance of bi-2212 silver-sheathed tape was studied experimentally. By using composite conductors, a 10 T HTSC coil which can be inserted into a NbTi-Nb/sub 3/Sn magnet of 15 T was designed, and the possibility of the application of HTSC to 30-40 T superconducting magnets is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
