Abstract :
A small saddle coil for quadrupole magnets was made in industry from BSCCO-2223 high temperature superconducting tape. The coil was made to help develop methods for winding the ends of small-aperture magnets. This coil has a radius of 35 mm. It was tested in liquid helium, and liquid nitrogen. Voltage taps have been installed so that V-I characteristics of both straight and curved elements can be examined. The performance of the coil is compared to short sample measurements of pieces of conductor taken from the start and finish of the windings.
