Second sound resonators and tweezers as vorticity or velocity probes : fabrication, model and method
Eric Woillez, Jérôme Valentin, Philippe-E. Roche
An analytical model of open-cavity second sound resonators is presented and validated against simulations and experiments in superfluid helium using a new resonator design that ach…
Local measurement of vortex statistics in quantum turbulence
Eric Woillez, Jérôme Valentin, Philippe-E Roche
The density fluctuations of quantum vortex lines are measured in a turbulent flow of superfluid He, at temperatures corresponding to superfluid fraction of 16%, 47% and 81%. The pr…
Cooling with a subsonic flow of quantum fluid
Pantxo Diribarne, Bernard Rousset, Yuri A. Sergeev +3
Miniature heaters are immersed in flows of quantum fluid and the efficiency of heat transfer is monitored versus velocity, superfluid fraction and time. The fluid is He helium…
Extended point defects in crystalline materials: Ge and Si
Nick E. B. Cowern, Sergei Simdyankin, Chihak Ahn +10
B diffusion measurements are used to probe the basic nature of self-interstitial 'point' defects in Ge. We find two distinct self-interstitial forms - a simple one with low entropy…
