A method for progressively introducing current into, or removing current from, a superconducting coil mounted on a former, in which the coil vibrates relative to the former. Each net has a ground capacitance, a coupling capacitance, and a resistance. The OMS\u2122 solution is comprised of Mega-Tags, a battery testing and data acquisition device, and web-based software. In a process of cooling the resin, the temperature control is performed so that the temperatures of the fixed mold and the movable mold are maintained between an upper limit TUa and a lower limit TLa of a temperature range effective for resin annealing by stop of supply of the cooling medium and the supply and stop of the heating medium.
