Dramatic advances in diagnostic measurements may accelerate developments in many fields.  Traditional ultrasonic measurements are used primarily to define geometries, that is find flaws.  Materials Characterization (MC), on the other hand, gives the engineer physical properties needed for model validation to predict future performance.  Traditionally, MC comes from destructive measurements.  Luna's MC is assessing adhesive materials, composites, advanced metal alloys, and micro/nano structural architectures.  In these cases, time dependant material changes are used to evaluate aerospace and bio materials. 

Luna's high resolution ultrasonic systems see changes in acoustic parameters to better than 100 parts per billion.  Use of this system has already enhanced the utility and value of ultrasonics for numerous aerospace application areas including microstructure-based elastic effects, texture, heat treatment, impact damage, fatigue and manufacturing defects.  Biological applications are moving forward, with FDA approval received for our EDAC™ system and delivery to NIST of our radiation dosimetry monitor prototype.  In this meeting with JLab, we will discuss these capabilities, review recent applications in solids, liquids, slurries, and gases to explore potential interest with your staff.
