ANSYS simulations

Summary of field simulations for the 30D72 magnet from BNL

The BNL 30D72 magnet has been modeled in Ideas based on the original drawings of the iron cores. The model was imported into ANSYS as a step fiel and used as the basis of a magnetostatic simulation. The side view o the right only shows the left half of the magnet. In the simulation a symmetry plane is inserted in the z=0 plane and only half the magent is calculated.

Detailed drawings of the coils were not available so approximatate values needed to be determined from the known specifications of the magnet. The specification states that the magnet will have a maximum field of 2t at an operating current of 2500 A. The number of turns was adjusted to match this.
