Abstract

The authors have developed a technique for uranium isotope ratio measurements of powder samples in field settings. Such a method will be invaluable for environmental studies, radioactive waste operations, and decommissioning and decontamination operations. Immediate field data can help guide an ongoing sampling campaign. The measurement encompasses glow discharge sputtering from pressed sample hollow cathodes, high resolution laser spectroscopy using conveniently tunable diode lasers, and optogalvanic detection. At 10% {sup 235}U enrichment and above, the measurement precision for {sup 235}U/({sup 235}U+{sup 238}U) isotope ratios was {+-}3%; it declined to {+-}15% for 0.3% (i.e., depleted) samples. A prototype instrument was constructed and is described.

Determination of Actinide Isotope Ratios Using Glow Discharge Optogalvanic Spectroscopy

Conference Young, J; Shaw, R; Barshick, C; ...

Diode-laser excited optogalvanic spectroscopy (OGS) of a glow discharge has been utilized to measure U-235/U-235 + U-238 isotope ratios. This ``optical mass spectrometric`` measurement has been demonstrated for a number of samples including uranium oxide, fluoride, and metal. Various diode-laser accessible atomic transitions in the 775 to 835 nm region have been evaluated; these transitions were chosen by considering OGS sensitivity and isotope shift. Using the 831.84 nm uranium line, for example, it was possible to measure the U-235/U-235 + U-238 isotope ratio (0.0026) of depleted uranium samples. A prototypical field instrument to make these measurements has been assembled andmore »« less

Isotopic analysis of uranium using glow discharge optogalvanic spectroscopy and diode lasers

Journal Article Barshick, C; Shaw, R; Young, J; ... - Analytical Chemistry (Washington); (United States)

A hollow cathode glow discharge has been coupled with tunable lasers for isotopically selective excitation of gaseous uranium atoms produced by cathodic sputtering. A CW argon ion laser-pumped titanium:sapphire ring laser and a semiconductor diode laser were employed. Optogalvanic detection of the discharge atom population allowed identification of [sup 235]U at depleted, natural, and enriched abundances in uranium metal and uranium oxide samples based on the spectral signatures of two transitions. Isotope ratio measurements were precise from run to run (internal precision) to better than +1% relative standard deviation at 1[sigma]; external precision (sample to sample) was on the ordermore »« less

Glow discharge diode laser-based spectroscopy for measurement of uranium isotope ratios

Conference Barshick, C; Young, J; Shaw, R; ...

Although isotopic analysis has traditionally been the forte of mass spectrometry, several other techniques have been developed for this purpose, including decay-counting and methods that rely on the accessibility of optical transitions for isotopic selectivity (e.g., laser-induced fluorescence and optogalvanic spectroscopy). We have been investigating optogalvanic spectroscopy, and have focussed on the use of a dc glow discharge for atomization and ionization, a demountable discharge cell for rapid sample exchange, and diode lasers for isotopically selective excitation. Our goal is a fieldable instrument that provides useful uranium isotope ratio information. Precision and accuracy have been evaluated for several optical transitions.more »« less
Diode laser excited optogalvanic spectroscopy of glow discharges

Conference Barshick, C; Shaw, R; Ramsey, J

The development of diode-laser-excited isotopically-selective optogalvanic spectroscopy (OGS) of uranium metal, oxide and fluoride in a glow discharge (GD) is presented. The technique is useful for determining isotopic ratios of {sup 235}U/({sup 235}U + {sup 238}U) in the above samples. The precision and accuracy of this determination is evaluated, and a study of experimental parameters pertaining to optimization of he measurement is discussed. Application of the GD-OGS to other f-transition elements is also described.
