Spectrometer magnets for use in satellite and balloon-borne cosmic ray experiments are subject to strict limits on mass and volume. Typically, the particle detectors are mounted adjacent to the outer boundary of the magnet package, rather than within its bore. Optimizing the distribution of ampere-turns radically, in a high alpha, low beta winding cross section places more ampere-turns in closer proximity to the detector volume. In additions, this winding configuration results in lower peak fields and lower stresses in the windings. Utilizing the bore volume for support structure can save a factor of two in structural mass. The resulting magnet package presents a full-diameter flat surface toward the detector space
