Observation of roton emission from a quantized vortex
A. Lester, N. Morrison, F. Novotny +5
Turbulence in inviscid quantum fluids offers unparalleled access to the universal principles of non-equilibrium dynamics, spanning a vast range of length scales from macroscopic fl…
Aluminum nuclear demagnetization refrigerator for powerful continuous cooling
Matthias Raba, Sébastien Triqueneaux, James Butterworth +10
Many laboratories routinely cool samples to 10 mK, but relatively few can cool condensed matter below 1 mK. Easy access to the microkelvin range would propel fields such as quantum…
A low-frequency, high-amplitude, torsional oscillator for turbulence studies in quantum fluids
A. M. Gu'enault, P. V. E. McClintock, M. Poole +5
We describe a new type of torsional oscillator, suitable for studies of quantum fluids at frequencies of Hz, but capable of reaching high velocities of up to several c…
Superconducting aluminum heat switch with 3 n equivalent resistance
James Butterworth, Sébastien Triqueneaux, Šimon Midlik +9
Superconducting heat switches with extremely low normal state resistances are needed for constructing continuous nuclear demagnetization refrigerators with high cooling power. Alum…
Very low resistance Al/Cu joints for use at cryogenic temperatures
Sébastien Triqueneaux, James Butterworth, Johannes Goupy +4
We present two different techniques for achieving low resistance (20 n) contacts between copper and aluminium at cryogenic temperatures. The best method is based on gold…
Thermal Radiation in Rayleigh-Bénard Convection Experiments
P. Urban, T. Králík, P. Hanzelka +4
An important question in turbulent Rayleigh-Bénard convection (RBC) is the effectiveness of convective heat transport, which is conveniently described via the scaling of the Nussel…
