I think this looks consistent with the CTD data.

Jim,

We set up an experiment to determine the Coefficient of Thermal Expansion
(CTE) of the copper/epoxy composite.  We measured the contraction of an
impregnated bar when cooled from room to liquid nitrogen temperature (294
to 77 K).  The following data was recorded.

Room temperature - 21C (294 K)
Room temperature length of bar - 32.424"
LN2 temperature length of bar - 32.323"

The calculated CTE is  1.435 x10E-6 (in/in per degree Celsius)
