Observation of serrated deformation of superconducting magnets' windings
Abstract
Tensile and compression tests are performed to investigate the stress-strain behavior of superconducting windings as a unit. It is found that the stress-strain curve of superconducting windings is serrated at least at and below liquid nitrogen temperature, i.e. the serrations of superconducting windings take place at temperatures much higher than those for serrations of short samples of superconducting wires. At low values of current and mechanical load, the heat pulses generated at the serrations are insufficient to quench the winding. In windings the serrations begin at a stress level much lower than that of short samples of superconducting wires.
