Abstract :
In this paper we describe the design, fabrication and test of a model high field insert magnet utilizing react and wind BSCCO-2212 surface coated (SC) tape conductors. An added central field of 1.2 T and 1.08 T was achieved at 4.2 K over a technologically useful 50 mm clear bore in applied background fields of 0 and 5.5 T respectively, In addition, we report the results of high field measurements to 17.5 T made on a double pancake coil module fabricated using react and wind BSCCO-2212 powder-in-tube (PIT) tape. The insert magnet and pancake coil modules are part of a continuing effort to demonstrate the application of HTS conductors for the generation of the high magnetic fields required for NMR systems operating at the 1.0 GHz level.
