Chemical Forensics and Signature Science
Research and development of new instrumentation and techniques for Programmatic, Energy, Global Security and Commercial applications.
Laser-Induced Breakdown Spectroscopy (LIBS)
LIBS is a laser based technique that involves the use of a focused pulse laser beam to generate a microplasma. The emission from the plasma is wavelength resolved using a spectrograph / detector / computer system to determine the elemental composition of the samples of interest.

Direct Measurements of plutonium using X-Rays
- The goal of this research effort is to develop a novel X-ray based method for improved Pu assay for safeguards applications, monitoring spent fuel reprocessing plant processes, and insuring more accurate Pu accounting.
- The advantage of this method over existing ones is the direct measurement of actinide elements.
