When a magnetic field or temperature quenches a superconductor, all of
the energy carried by the superconductor is immediately dissipated at
the quench location. This has disasterous consequences, often explosive
ones, depending on how much energy is in the system. One standard
solution is to clad the superconductor with copper so the current
bypasses the quench location and the heat is diffused into the current
carrying parts of the copper cladding.
