Abstract:The development of measurement methodologies to detect and monitor nuclear-relevant materials remains a consistent and significant interest across the nuclear energy, nonproliferation, safeguards, and forensics communities. Optical spectroscopy of laser-produced plasmas is becoming an increasingly popular diagnostic technique to measure radiological and nuclear materials in the field without sample preparation, where current capabilities encompass the standoff, isotopically resolved and phase-identifiable (e.g… Show more
“…Optical spectroscopy techniques using laser-produced micro-plasmas including laser absorption spectroscopy (LAS), laser-induced fluorescence (LIF) spectroscopy, and laser-induced breakdown spectroscopy (LIBS) are viable methods applied towards the standoff characterization of radiological and nuclear materials. 1 Applications range from the spectrochemical assay of gaseous UF 6 for safeguards verification of uranium enrichment levels 2,3 to the monitoring of fission products generated during operations for molten salt reactors. 4 Interactions between aerosols and laser filaments are studied to develop optical signals towards the atmospheric sensing of releases of radiological material.…”
