A set of universal scaling relations is presented describing the propagation of quench in CICC (cable-in-conduit superconducting magnet) magnets. Four distinct types of behavior are possible depending upon the length of the coil and the magnitude of the quench induced pressure rise. The boundaries separating these regions can be simply expressed in terms of L/sub q/ the initial quench length, and J the stabilizer current density, the two parameters likely to vary during standard operation. The phenomenon of thermal hydraulic quenchback (THQB) is also considered. It is shown that the conditions for the onset of THQB can also be cast as a set of universal scaling relations and easily superimposed on the quench diagram.ETX
