The performance of BSCCO racetrack windings for a common coil dipole

摘要

The first of a series of 90 cm long racetrack shaped coils has been tested at 77 K and 4.2 K in a common coil configuration. The conductor used was selected from a number of available lengths by testing in liquid nitrogen in pancake form. The performance of this coil is compared with shorter versions fabricated from similar conductor.
