摘要:

A micronic‐size hot wire anemometer operating at cryogenic temperatures (4 K) has been developed; using superconducting and resistive thin films, its electrical resistance is very sensitive to the velocity of a gaseous4He subsonic jet. The fabrication procedure is described and the measured characteristics are compared with a simple thermal equilibrium model.
