Film Flow Driven by van der Waals Forces

To examine film flow driven by van der Waals forces, a film detector is required that combines a large surface area with a narrow flow path for film formation from the helium bath. Furthermore, we require that the film formation rate by superflow be far in excess of the film formation rate by condensation. Evidence that the latter criterion applies in our experiments is given below; we have also examined evaporation and condensation directly, as described in an accompanying paper.1
