The current carrier is electrically connected at its ends to two normally conducting current supply lines. The cooling medium is subcooled from the storage container to a temperature below its boiling temperature and is supplied to the cryostat by means of a cooling medium inlet, brought into thermal contact with the superconducting current carrier and subsequently discharged by means of a cooling medium outlet of the cryostat. According to the invention, it is proposed that the cooling medium from the cryostat is used for cooling at least one of these normally conducting current supply lines.)
