    Preparation of ultra small samples for optical and microprobe analysis (1973)
    In:  Other Sources
    Details
    Publication Date: 2011-08-16
    Description: This paper describes a simple but satisfactory new method for the preparation of tiny, varied and specialized specimens for electron or ion-microprobe analysis developed over the past five years. Microtektites, individual chondrules, single grains, blebs from lunar samples and meteoritic minerals have been prepared by this technique. A description of the preparation of these usually difficult samples from the initial mounting through the various polishing steps to their final polish is presented in detail. The procedures used to prevent any contamination of these specimens by the polishing agents and to prevent cross contamination to the other samples used for geochronology studies are presented.

    Design and construction of high-sensitivity, infrared bolometers for operation at 300 mK (1992)
    In:  Other Sources
    Details
    Publication Date: 2019-08-14
    Description: The design and construction of 300-mK composite bolometers developed for millimeter-wave astronomical observations are described. Graphite fibers are used as the electrical leads for the thermistor to reduce the thermal conductance and heat capacity associated with the leads. A mechanical suspension made of Nylon fibers provides the required thermal conductance. Electrical noise equivalent powers below 1 x 10 exp -16 W/sq rt Hz have been achieved for detectors with thermal time constants of 11 ms. The detectors were installed in a millimeter-wave photometer and used to perform observations of the cosmic microwave background from a balloonborne platform. The flight performance was consistent with the measured laboratory properties.
