The stability of the new high temperature superconducting oxides has been analyzed using the methodology developed over the last 25 years for conventional Type II superconductors. The results are presented in graphical form for the temperature range from 4 to 100 K. For a 90 K superconductor the first flux jump field peaks above 7T at 60 K. The adiabatic stability limit increases dramatically. THe linear dimension of the minimum propagating zone increases by a factor of 3 to 5, and the quench propagation velocity drops by 4 orders of magnitude. The high temperature superconducting materials will, therefore, have much higher stability than conventional Type II superconductors; their high flux jump fields make ultra-fine multi-filamentary conductors unnecessary, and improve the outlook for tape conductors; the energy to create a propagating zone is increased; but methods of coil protection will have to be modified.
