Summary: | Joule heat generated by resistive elements of cryogenic micro- and
nanodevices often originates boiling of the cooling cryogenic liquids (helium,
nitrogen). The article proposes an experimental method to explore the dynamics
of the formation and development of a single vapor bubble in cryogenic liquid
by sensing the temperature change of a superconducting thin-film microbridge
being in the resistive state with single phase-slip center or line. It serves
both the source of heat for generating single bubbles and the surface
temperature sensor due to its temperature-dependant excess current. The average
bubble detachment rate and the average single bubble volume were experimentally
determined for nucleate helium boiling. The obtained values are in good
agreement with the data of other authors found in literature. |
