HIGH TEMPERATURE SUPERCONDUCTING RACETRACK COIL

摘要

A racetrack shaped high temperature superconducting (HTS) coil is fabricated by layer winding HTS tape (18) under tension on a precision coil form with a binder such as pre-preg filament-ply interlayer insulation. The coil form includes a racetrack shaped bobbin (12), two side plates (14) and a series of blocks (16) that define the outside surface of the coil. The outside surface of the winding is over- wrapped with a copper foil bonded to heat exchanger tubing. The coil is baked in the coil form to cure the epoxy then released from the coil form. The resulting coil structur e is a strong winding composite built to close tolerance dimensions.
