High-resolution laser spectroscopy of gas phase species, including laser absorption, laser-induced fluorescence, and several resonant photoionization methods.
Optical system work for beam alignment and diagnostics in support of the above.
Techniques for producing atomic/molecular beams of gas-phase species from refractory metals, namely, laser ablation source design, high temperature vacuum furnace source design.
Data acquisition and analysis software architecture, typically using the LabVIEW programming language.
High vacuum (10-8torr) system construction, maintenance, and operation.
Bulk radiological solid material handling (U, Pu) in mg-g quantities, i.e., source loading for gas-phase actinide spectroscopy.
