Optimization of multiwire coil ends having 45 degree bends

Multiwire is the name of a proprietary process for affixing small-diameter wires to a flat substrate using digitally controlled machinery. It is currently being used to wind trim coils for the SSC (Superconducting Super Collider) dipoles on a flexible substrate which is wrapped around the beam tube. The current multiwire process does not permit a change in direction of the wire other than 45 degrees . The author investigates the location of 45 degrees bends in the flattened coil along straight lines in such a way as to eliminate or reduce higher harmonics in the ends.<>
