Thermal properties of molybdenum below 1 K with application to ultracryogenic resonant-mass gravitational wave detectors
- Department of Physics, Santa Clara University, Santa Clara, California 95053 (United States)
Measurements of the thermal conductivity and specific heat of commercial 99.95{percent} purity annealed polycrystalline molybdenum in the temperature range of 0.1{endash}1 K are reported. These thermal data and other published data on molybdenum and aluminum{endash}magnesium alloys are used to calculate and compare cool-down and steady state thermal response of 1 kHz ultracryogenic resonant-mass gravitational wave detectors made of these materials. At temperatures below 100 mK, the Mo is shown to be far superior to the 5056 Al{endash}Mg alloy with regard to temperature homogeneity in the resonant mass at the expected levels of residual heat leak. {copyright} {ital 1997 American Institute of Physics.}
