Abstract

The invention concerns a magnet system (1) for charging of a superconducting magnet coil (3). The magnet system (1) is characterized by control means (4) for reading-in and controlling which read-in data of a storage medium (7) associated with the superconducting magnet (3) into a power supply (2) and which control the charging of the superconducting magnet coil (3) by the power supply (2) using the read-in data. The magnet system (1) facilitates a fully automatic, safe and rapid charging of a superconducting magnet coil (3) and guarantees better reproduceability and an optimal charging process.
