Design of superconducting high energy beam line dipole-magnetostatics

Three relatively distinct designs of superconducting beam line dipoles have evolved at Fermilab. Two follow from Energy Doubler/Saver considerations and one from POPAE considerations. Suitable end arrangements are placed on each coil to eliminate the field rise in the end conductors. An adjustment of the conductor locations within the body of the magnet then permits the elimination of sextupole and decapole terms in the longitudinally integrated magnetic field. The three designs being presently pursued are presented
