Executive Summary

The goal of this field-expanding research is to develop and employ diagnostics capturing, quantifying, and characterizing the temperature and chemistry of high explosives in situ during reaction to gain necessary data to create a unified, predictive, computational model. The results will dramatically impact stockpile stewardship activities and nuclear weapons detection and interdiction technologies for non-proliferation and counterterrorism.
