We specialize in non-destructive measurements of Normal Zone Propagation Velocity (NZPV) in superconducting REBCO tapes and cables.
Why NZPV matters:
In REBCO tapes, critical current inhomogeneities can trigger hot spots. Having a too low NZPV concentrates heat locally, increasing the risk of having destructive hot spots. NZPV is a metric to determine how fast a quench propagates, which is crucial for quench detection and protection strategies for high-field superconducting magnets, high-power superconducting cables, superconducting motors, etc.
Our NZPV setup:
Pulsed current source, up to 2000 A, with durations from ms to hundreds of ms
Temperature range from 65 K to 77 K
Spatial resolution down to 1 mm along meter-scale samples
