BATTERY OPERATION OF SUPERCONDUCTING MAGNET

Battery energy can be used for superconducting magnet operation if the current of the battery is controllable, Several current-control metho ds are discussed:. variation of electrolyte temperature, variation of exposed electrode area, and the mechanical switching of cells, A circu it for continuously controlling the current using mechanical switches was proposed and a demonstration experiment, in which ''D'' size Ni-Cd batteries were used for the smooth control of the current up to 45 A, was successfully performed.
