Progress on levitating a sphere in cryogenic fluids
Manuel Arrayás, Francis Bettsworth, Richard Haley +5
We present the working prototype of a levitation system designed for investigation of flows in cryogenic helium fluids. The current device allows the levitation of a superconductin…
Thermal transport in nanoelectronic devices cooled by on-chip magnetic refrigeration
S. Autti, F. C. Bettsworth, K. Grigoras +8
On-chip demagnetization refrigeration has recently emerged as a powerful tool for reaching microkelvin electron temperatures in nanoscale structures. The relative importance of coo…
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…
