Force free design of super-ferric beam line magnet

A force free design of super-ferric beam line magnet is proposed. Super-ferric magnets use induction efficiently to produce magnetic field. The problem of super-ferric magnet has been the electromagnetic force that increases the heat load of the magnet and eliminates the advantage of the energy saving of superconductivity. This design balances out the electromagnetic force works on the conductor and realizes the very light support of the conductor resulting a very small cold mass and heat load. Beam line magnet can be much more economical both in construction and operation. Shifting of conductor position, asymmetric pole width and adjusting holes in the pole piece are the major force balancing techniques. Testing is planned using VLHC test facility at Fermilab.
