Superconducting X-ray lithography 180 degrees bending dipole magnetics analysis methodology

The Superconducting X-ray Lithography Source (SXLS) being built at Brookhaven National Laboratory requires two superconducting bending magnets. The authors describe the magnetic analyses completed to support and direct the design of magnets capable of successfully meeting the system requirements. Because of the diversity of the effects investigated a number of analytical techniques were necessary. Each of the effects and the analytical approach chosen are outlined. The magnetic field calculation approach and verification are presented. To verify the satisfaction of requirements, field calculations to seven significant digits were necessary. The effects of magnetic permeability of magnet materials, eddy currents, superconductor magnetization, current leads, splices, structural deflection, and manufacturing tolerances were calculated in addition to the current density field calculations.<>
