Abstract
A method for charging a magnet arrangement having a superconducting tape conductor with a first transition temperature in a cryostat device. The magnet arrangement is temperature-controlled to a first pre-operating temperature between the first transition temperature and the operating temperature, a first pre-operating current is excited, the magnet arrangement is cooled to operating temperature and a first operating current is excited. The magnet arrangement has a second magnet winding composed of a second superconductor material with a second transition temperature above the operating temperature and at least 15 K below the first transition temperature, wherein a second operating current in the second magnet winding is excited at the latest after cooling of the magnet arrangement to the operating temperature, and with the second operating current the second magnet winding generates a second operating magnetic field in the volume of the first magnet winding.
