## Abstract

Superfluid \\4he atoms are injected (withdrawn) asymmetrically into (from) a chamber filled with solid \\4he. Two in situ capacitance pressure gauges are located at the ends of the solid helium sample at different distances from where the superfluid meets the solid \\4he. The pressure change kinetics are slower at the more distant gauge. This demonstrates the presence of a mass flux bottleneck inside the solid helium sample. The temperature dependence of the maximum flux reveals a crossover and this is discussed in the context of phase slips on quasi-1-D pathways.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
