Abstract
Examination of the criteria governing the design of superconducting adiabatic windings shows that the extrapolation of the design of a magnet storing 6 MJ of energy to higher energies can lead to adiabatic windings of about the same size as their cryostable equivalents. The criteria considered are i) stability against the energy released by epoxy cracking, ii) quench hot-spot temperature, iii) quench voltage, iv) self-field instability and v) temperature rise due to steady heat dissipation within the winding. The dimensionality of the quench in an adiabatic winding is seen to affect the extrapolation. A winding in which the quench propagates for a significant time in three mutually perpendicular directions leads to the highest winding current densities, but to less tolerance for distributed internal dissipation, Extrapolation of operating current may be limited by self-field instability to lower values than are usual in large systems.
