Abstract

A detailed analysis of phase-slip observations in superfluid4He in a double-hole hydromechanical resonator fitted with a micro-aperture yields the remanent current trapped in the superfluid loop threading the two holes. The value of this bias current remains constant in each given cool-down below the λ point. Its value at each cool-down appears to be fixed at random. It can be determined to about a hundredth of the circulation quantum. This is the present practical resolution of the double-hole resonator used as an absolute gyrometer.
