✦ Synopsis

improve thermal contact between components on which no pressure is exerted. A very thin layer of grease between the contacts improved Q tenfold until the greases solidified (270 ° K and 230 ° K for the 'N' and 'T' greases respectively), whereupon conduction fell abruptly to a value which was significantly lower than that of the 'dry joint'.
