Single-Turn Magnet With an Additional Balanced Winding and Flux Concentrators

The balanced winding displaced in the cavity, the magnet provides the possibility for obtaining the stronger magnet field without enhancing mechanical stresses in the conductors. The model of such a system is the single-turn magnet with an additional triple-thread spiral winding. The equilibrium condition with respect to the radial force takes place at definite values of the axial current and pitch of the turns. In order to decrease the transverse field provoking the azimuthal force, the correction system in the form of cylindrical conductors with slits has been used. The discharging of the end part of the additional winding from the axial force is achieved using the flat concentrators of the flux.
