The motion of tracer particles in turbulent superfluid He down to the zero-temperature limit
C. O. Goodwin, M. J. Doyle, J. A. Hay +4
An injection system for polymer particles, with diameters ranging from 1 to 6 m, has been developed for visualizing flows in superfluid He at temperatures down to 0.14 K. Us…

Apparatus to visualize flows in superfluid He below 1 K
I. Skachko, J. A. Hay, C. O. Goodwin +4
We describe a versatile apparatus for optical observations of experimental processes at temperatures down to 0.1 K. The cooling is achieved by a wet cryostat with a dilution refrig…
