Description

The propagation velocity of normal zones along bare technical NbTi-superconductors, cooled with saturated and pressurized HeII was measured at bath temperatures of 2.0 K and magnetic fields of 1.77 and 2.5 T. Although in saturated HeII propagation velocities up to 18 m/s were obtained, in pressurized HeII no propagation was observed up to transport currents close to Ic. Furthermore transient heat transfer from thin bare wires to HeII was investigated with a time resolution in the μs-range. The results are discussed with regards to a theoretical model of quench dynamics. (orig.)
