A simple heat exchanger using silver powder for cooling pure liquid 3He is described. The temperature difference across the heat exchanger was less than 5#K at the superfluid transition of 3He with a thermal flux of 0.06 nW.
We have investigated a series of Pt black sinters for use as heat exchangers to cool liquid or solid helium to temperatures below 1 mK. They had thicknesses between 60 and 80 lm and speciยฎc surface areas up to 39.7 m 2 /g and 304 m 2 /cm 3 . The sintering was on highly polished Cu surfaces of 12X7 ร
