SENSING AND CHARACTERIZATION TECHNOLOGIES AT LOS-ALAMOS-NATIONAL-LABORATORY

We describe four sensing and characterization technologies recently de veloped at Los Alamos National Laboratory; a select set of mass spectr al and optical techniques is emphasized. This work describes new, or n ewly developed, technologies which can be used for on-site, at-line an d laboratory analyses. These include two each of optical- and mass spe ctrometric-based systems. We describe first a field deployable mass sp ectrometer, based on an ion trap analyzer, and variants of that system . We then describe a hand-held, battery-operated optical spectrometer, usable in either absorption, or fluorescence excitation mode. A laser -based mass spectrometer is also described, which used a minimal tunab le laser system, and a time-of-flight mass spectrometer. Finally, a Ze eman effect optical diffractomer is described.
