Novel Micro-manipulation methods for radioactive particel isolation and characterization with energy-filtered electron microscopy


EMSL Project ID
11990

Abstract

Successfully designing the next generation of nuclear power plants will require developing improved methods for characterizing and examining radioactive materials. This will include sub-micron phase identification using such analytical instruments as analytical energy-filtered transmission electron microscopy and imaging. The main advantage of this technology over other conventional spectroscopic methods, such as x-ray absorption spectroscopy or x-ray photoelectron spectroscopy, is that the electronic density of states in an extremely small volume of material can be probed. Furthermore, because of the high spatial resolution in this technology, analyses from very fine grained and/or heterogenous materials can be achieved with confidence.
