We have constructed a large new dilution refrigerator for use with the new Lancaster nuclear cooling facility. The machine is housed in a purpose-rebuilt suite of rooms and has been designed to have a very low base temperature, a very low heat leak e

We describe a compactly designed dilution refrigerator with closely packed, vertical heat exchangers. The refrigerator reaches a temperature of 2 mK and is easily constructed, since the sintered heat exchangers are straight units. Vibrating wire reso

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

We describe the philosophy and practice of a new method of nuclear cooling in which the copper refrigerant is immersed directly in the3He sample to be cooled using a guard cell configuration. The method has been used to cool liquid3He to ∼120 µK.

A lambda anomaly was observed in the nuclear heat capacity of a single crystal of praseodymium known not to order down to 1.8 K. The anomaly is associated with a cooperative magnetic ordering of the hexagonal-site nuclei at 25--30 mK of the type disc

Measurements of the mobility mu+ of positive ions in liquid 3He under a pressure of 1 bar in the temperature range 0.05 < T < 0.6 K exhibit a sharp peak in mu+(T) near 0.2K and irreproducible behaviour at lower temperatures.

We have used our immersed-refrigerant cooling method1,2, previously used only to cool 3He–4He solutions3,4, to cool a sample of moderately pure 3He. In the preliminary experiment reported here we have achieved an extremely low helium temperature, c
