Abstract

Once the production of high quality long length Bi(Pb)-2223/Ag tapes have been achieved considerations such as fabrication into practical applications without degrading the performance of the tape become the major issues. Here, the application involves the construction of class II coils and magnets. The main problems concerned are usually related to the winding procedures (e.g. wind-react and react-wind), the insulating material, the construction or stacking of coils if they are pancake-shaped and the study of quench propagation parameters. This paper investigates these issues in coil design and construction by means of measurement techniques from small scale coils and magnets made from high-T/sub c/ superconducting Bi(Pb)-2223/Ag composite tapes.
