Stability of an uncooled segment of a high-temperature superconductor
Abstract
If the level of a liquid cryogen inadvertently falls below the top of a magnet winding, it may expose a segment of the conductor. Depending on the length of the uncooled segment and on how the matrix resistivity varies with temperature, zero, one, or two steady normal states may be possible. The stability of the various steady states, the conditions under which they appear, their energies of formation, and the voltages they produce are studied in this paper.
