Hardware Acquisition For Experimental Studies Of Multiple Scattering Of Elastic Waves In Geophysics

这项拨款用于购买实验室设备以研究弹性波多次散射和共振超声光谱学。该设备包括一个隔振光学工作台、一个16位高速数字示波器板、一个任意波形产生板、一个锁相放大器和一个低噪声前置放大器。这种新设备将使我们能够进行各种测量，旨在理解和利用弹性波和共振超声的多重散射，以表征地质材料的特性。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。该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特性实验室共同使用。它也可用于CSM地球物理系的本科和研究生教学和研究

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.***
