Query: Properties of selected structural and flat flexible cabling materials
  for low temperature applications   We present measurements of the low temperature thermal conductivity for
materials useful in the construction of cryogenic supports for scientific
instrumentation and in the fabrication of flat flexible cryogenic cabling. The
materials we measure have relatively low thermal conductivity. We present a
method for measuring the heat transfer coefficient of flat cabling and show,
using an example, that the thermal conductivity of a flex cable is reasonably
well predicted by composing the thermal conductivities of its constituent
material layers. Room temperature physical and mechanical data is given for the
materials studied, as well as an overview of relevant materials science and
manufacturing details. Materials include Timet Ti 15-3 and Ti 21S, Materion
alloy vit105 (LM105) in amorphous state, ATI Metals Nb-47Ti, Johnson Matthey
nitinol (NiTi), Mersen graphite grade 2020, DuPont Pyralux coverlay and Vespel
SCP-5050, and Fralock Cirlex polyimide sheets. All data is in the temperature
range 0.5 to 2 K, and up to 5 K for SCP-5050.
