Superconducting OHMIC-heating coils for the Argonne TEPR design study

A system of air-core superconducting ohmic-heating coils was studied for the Argonne TEPR design. The OH coil requirements, the basis for the choice, and a suitable conductor are described. A 3.6 m diameter, 13 m long solenoid plus ten other coils with diameters up to 23 m provide (together with the equilibrium coils) the needed 110 volt-sec flux change while producing little magnetic field at the plasma region or at the toroidal field coils.
