    Adiabatic Melting Experiment on Helium Mixtures: Status and Prospects

    We describe the improvements made to our earlier experiment, aiming to cool saturated helium mixtures at the melting pressure to ultra-low temperatures in the microkelvin regime. Cooling is produced by dissolv...

    Phase diagram of turbulence in superfluid 3He-B

    In superfluid 3He-B mutual-friction dam** of vortex-line motion decreases roughly exponentially with temperature. We record as a function of temperature and pressure the transition from regular vortex motion at...

    Measurement of Turbulence in Superfluid 3He-B

    The experimental investigation of superfluid turbulence in 3He-B is generally not possible with the techniques which have been developed for 4He-II. We describe a new method by which a transient burst of turbulen...

    Vortex Formation in Neutron-Irradiated Rotating Superfluid 3He-B

    A convenient method to create vortices in meta-stable vortex-free superflow of 3He-B is to irradiate with thermal neutrons. The vortices are then formed in a rapid non-equilibrium process with distinctive charact...

    Superfluid He in Rotation: Single-Vortex Resolution and Requirements on Rotation

    The present generation of rotating refrigerators, which are used for the study of quantized vorticity in helium superfluids, are often capable of cooling to mK temperatures and rotate up to ∼ 1 rev/s. To achie...
