Mass flow through solid 4He induced by the fountain effect
M. W. Ray, R. B. Hallock
Using an apparatus that allows superfluid liquid 4He to be in contact with hcp solid \4he at pressures greater than the bulk melting pressure of the solid, we have performed experi…
Mass flux and solid growth in solid 4He: 60 mK - 700 mK
M. W. Ray, R. B. Hallock
We use the thermo-mechanical effect to create a chemical potential difference between two liquid reservoirs connected to each other through Vycor rods in series with solid hcp 4He…
Observation of thermo-mechanical equilibration in the presence of a solid 4He conduit
M. W. Ray, R. B. Hallock
We observe a thermo-mechanical effect when a chemical potential difference is created by a temperature difference imposed between two liquid reservoirs connected to each other thro…
Growth of solid hcp \^4He off the melting curve
M. W. Ray, R. B. Hallock
We report studies of the growth of solid hcp \4he at pressures higher than the bulk freezing pressure using a cell design that allows us to inject atoms into the solid. Near the me…
Observation of Mass Transport through Solid 4He
M. W. Ray, R. B. Hallock
By use of a novel experimental design, one that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the DC transport of mass through…
Observation of Unusual Mass Transport in Solid hcp 4He
M. W. Ray, R. B. Hallock
Solid 4He has been created off the melting curve by growth at nearly constant mass via the "blocked capillary" technique and growth from the 4He superfluid at constant temperature.…
