0111804ScalesThis grant provides support for the costs of acquiring laboratory equipment to study elastic wave multiple scattering and resonance ultrasound spectroscopy. The equipment includes a vibration-isolated optical bench, a 16-bit high-speed digital oscilloscope board, an arbitrary waveform generation board, lock-in amplifiers and a low-noise preamplifier.This new equipment will allow us to make a variety of measurements aimed at understanding and exploiting multiple-scattering of elastic waves and resonance ultrasound, in order to characterize the properties of geologic materials. The new equipment will complement our existing facilities for laser ultrasonics, in particular a scanning laser-Doppler vibrometer. The equipment will be housed in the Green Center at the Colorado School of Mines and jointly utilized by the Physical Acoustics Laboratory and the Rock Properties Laboratory. It will also be available for use in undergraduate and graduate teaching and research within the Geophysics Department at CSM.***

0111804比例尺这笔赠款支持购买研究弹性波多次散射和共振超声光谱学的实验室设备的费用。该设备包括隔振光学实验台、16位高速数字示波板、任意波形产生板、锁定放大器和低噪声前置放大器。这一新设备将使我们能够进行各种测量，目的是了解和利用弹性波和共振超声的多次散射，以表征地质材料的性质。新设备将补充我们现有的激光超声设备，特别是扫描激光多普勒振动仪。这些设备将被安置在科罗拉多矿业学院的绿色中心，并由物理声学实验室和岩石属性实验室联合使用。它还将用于CSM地球物理系的本科生和研究生教学和研究。*
