Current Redistribution in an SSC Strand during a Quench

  • O. R. Christianson
Part of the Advances in Cryogenic Engineering Materials book series (ACRE, volume 42)


Current redistribution in SSC strands due to current diffusion is calculated during a quench. Current redistribution occurs on the order of tens of microseconds. The copper core and sheath geometry and resistivity significantly affect the current redistribution. Heating in excess of steady state occurs while the current redistributes. This excess heating could contribute to enhanced quench propagation velocities. The excess heating due to current diffusion driven redistribution is compared to that in the theory of enhanced quench propagation.
