A design of a superconducting split-coil open gradient magnetic separator

Similarity properties of magnetic fields in axial coil systems are utilised together with extensive computations of various coil geometries to establish a set of design parameters α = 1.37, β1= 0.25 and β2= 0.625 defining the optimum split-coil configuration for the superconducting open gradient magnetic separator. An example of such a separator with magnetic force densities of 4.8 × 10⁸Nm^-3is presented and analaysed.
