Superconducting solenoid coil

Patent ·
OSTI ID:5409843
Disclosed is a superconducting solenoid coil of small size exhibiting a high degree of magnetic field uniformity. Emphasis is placed on the improvement in the magnetic field uniformity in a limited central active space of the coil, and, for this purpose, at least a portion of the cylindrical inner surface of the coil is shaped into a quadric configuration. The radius of curvature of this quadric portion is preferably less than a predetermined value relative to the axial total length of the coil.
