- Actually, you would be surprised: quite a bit of research has been done on
- thermal conductivity of materials at very low temperatures. Unfortunately,
- what people building equipment for cryogenic research are looking for
- is usually materials with *LOW* thermal conductivity, not high conductivity.
- However, tables exist of the thermal conductivities of many common materials
- at cryogenic temperatures. I had a paper here somewhere a few years ago,
- I'll see if I can find the reference.
