A Method for Driving an Oscillator at a Quasi-Uniform Velocity
D. E. Zmeev
We describe a simple way to drive an actuator, comprising a superconducting coil moving in a static magnetic field, at a quasi-uniform velocity. The main objective is to avoid osci…
A compact rotating dilution refrigerator
M. J. Fear, P. M. Walmsley, D. A. Chorlton +7
We describe the design and performance of a new rotating dilution refrigerator that will primarily be used for investigating the dynamics of quantized vortices in superfluid 4He. A…
Reconnections of quantized vortex rings in superfluid He at very low temperatures
P. M. Walmsley, P. A. Tompsett, D. E. Zmeev +1
Collisions in a beam of unidirectional quantized vortex rings of nearly identical radii in superfluid He in the limit of zero temperature (0.05 K) were studied using time-o…
Dynamics of quantum turbulence of different spectra
P. M. Walmsley, D. E. Zmeev, F. Pakpour +1
Turbulence in a superfluid in the zero temperature limit consists of a dynamic tangle of quantized vortex filaments. Different types of turbulence are possible depending on the lev…
Excimers He2* as Tracers of Quantum Turbulence in 4He in the T=0 Limit
D. E. Zmeev, F. Pakpour, P. M. Walmsley +7
We have studied the interaction of metastable He excimer molecules with quantized vortices in superfluid He in the zero temperature limit. The vortices were generated…
