Fermilab High-Field Option Popae Dipole - Magnetostatics

Magnetic field computations have been performed for a four-inch coil aperture 45 kG dipole magnet that may be utilized in a high-field option of POPAE. A cold iron version utilizing flat pancake coils has been explored to determine the magnetostatic effectiveness of a simple coil geometry. Suitable locations have been found for rectangular blocks of conductors each consisting of 280 turns of .040 in by .040 in conductor.
