Since the large Lancaster nuclear cooling refrigerator, conceived in 1978 and completed in 1981, is now well into its second decade we are planning a new machine. This paper outlines the main features and underlying philosophy of the new design based

The excitation gas in the A-phase at very low temperatures is concentrated in the region of the Fermi surface around the polar nodes in the gap and is thus almost one-dimensional. These low lying excitations are trapped by Andreev reflection in “di

We present a direct quantitative measurement of the Andreev reflection of a beam of quasiparticle excitations in the B-phase of superfluid3He in the ballistic regime. The beam, generated by a black-body radiator (which also acts as the detector), is

We have been interested in developing source-experiment-detector type quasiparticle beam experiments in superfluid3He for some time. Recently we have developed a new source and detector based on the quasiparticle equivalent of the blackbody radiator.

We report surprising new observations, both in Lancaster and in Moscow, of pulsed NMR in3He below 200 μK at 0 bar. At these low temperatures an extremely long induction decay signal of up to 25 s duration is observed. This signal develops from a sta

When a dilute solution of 3 He in 4 He is exposed to a magnetic field gradient and therefore contains both polarized and unpolarized particles, pumping can occur; 3 He atoms are pumped from the low field region to the high field region. A 3 He concen
