MECHANICAL heat switches are of considerable importance in low temperature work, for they often remain the simplest means by which a specimen can be cooled. In an investigation of this type of switch Jacobs and Starr ~ measured the thermal conductance between respective pairs of copper, silver, and
where Sag is the thermoelectric power of the silver normal and amounted to no more than 1 per cent of d V/dT. Values of S obtained in this way have an estimated uncertainty of about 4 per cent. The results are shown in Figure 1, where the solid circles represent the new thermoelectric power data. T
