The performance of BSCCO racetrack coils at 4.2 K

Small racetrack shaped coils have been fabricated from commercial 2223 and 2212 BSCCO tape conductors and tested in liquid helium at 4.2 K. These coils are insulated with Kapton film and provided with an array of voltage taps so that the characteristics of both straight and curved elements can be examined at various positions in the windings. The performance of the coils is compared to short sample measurements of the conductor. These small coils are prototypes of longer units which will be used in a test magnet designed to explore the potential of high temperature materials for the construction of dipoles and quadrupoles for future high energy accelerators and colliders.
