Abstract
A magnet coil arrangement comprising an actively shielded superconducting primary circuit ( ) comprising first and second magnet windings ( and ), and being wound e.g. in winding chambers ( and ) in a supporting body ( ) for generating a strong magnetic field in a working volume with a small magnetic stray field and a short circuited secondary circuit ( ) which is inductively coupled with the primary circuit ( ) and contains third and fourth magnet windings ( and ) is characterized in that the magnet windings ( and ) of the secondary circuit ( ) form an actively shielded magnet coil. This permits a simple and robust coil protection for actively shielded superconducting magnets during a quench wherein the superconducting magnet windings are reliably relieved and the magnetic stray field of the entire arrangement remains small.
