Tolerance of superconducting magnets to beam heating can be crucial. The magnets described produce a dipole field between parallel current sheets. Images in iron extend the sheets. The field is parallel to the current sheets so that high purity aluminum spacers can extend over the full length and height of the coil. High aluminum thermal conductivity and diffusivity results in locally produced heat being dissipated into helium over a large area. All magnets show little training with complete ''memory'' to approximately 100% of short sample. B induced quenching is not observed. The 2 m, 8/sup 0/ dipole coils do not quench at 4 T if the correcting coil is driven normal, dissipating >1 kW. Intralayer quench propagation induced by 30 GeV protons is described. A 1 m, 6 T pulsed dipole first quenched at 5 T. Pulsing losses at 0.5 T/sec are small.
