Tensile properties of 1050 aluminum plate at cryogenic temperatures.

Dielectric properties of PbNb2O6 ferroelectric ceramics at cryogenic temperatures

Refractive Index of ZnSe at Cryogenic Temperatures†

This report describes an extensive data set on the refractive index of ZnSe that provides full high resolution coverage of the CRIRES operating range in both wavelength and temperature. By combining our prototype instrument model of CRIRES with these data our project to provide wavelength calibration for IR Echelle spectrographs (WIRE) has reached an important milestone and is ready to support ...

Measurements of the Material Properties of a Laminated Piezoelectric Stack at Cryogenic Temperatures

Future NASA missions require cooling of large structures in space. One class of thermal management solutions for providing controlled, distributed cooling would utilize actively controlled micro-scale valves that are integrated with heat exchangers and sensors in order to provide independent, local temperature control. The most attractive actuation method for these micro-valves is a multilayer ...

Mechanical quality factor of a sapphire fiber at cryogenic temperatures

A mechanical quality factor of 1.1× 107 was obtained for the 199Hz bending vibrational mode in a monocrystalline sapphire fiber at 6K. Consequently, we confirm that pendulum thermal noise of cryogenic mirrors used for gravitational wave detectors can be reduced by the sapphire fiber suspension.
