Radial Distribution of Superfluid Vortices in a Rotating Annulus
An annular geometry is convenien for theoretical1,2 and experimental3–5 studies of the equilibrium state of superfluid helium in a rotating container. Previously we reported studies of the radial distribution of superfluid vortices in an annulus with a width of 1.79 mm.5 Standing waves of second sound were used as probes of the vortex distribution. In this paper we report on extensions of the work to annuli with widths of 1.27 and 0.75 mm.
