Abstract

We report the results of an experimental investigation of the nature of the vortex-boundary interaction and its role in the spin-up problem of superfluid He4. We find evidence for two independence vortex-drag mechanismsa drag associated with vortex lines pulling against pinning sites with a force equal to the line tension and a viscous drag associated with vortex motion through the normal-fluid Ekman layers.
