My primary research emphasis is the use of
low-temperature, atmospheric glow discharges to modify
and decontaminate surfaces. This includes the
modification of textiles, the deactivation of bacterial and viral
surface contaminants on food packaging and the
sterilization and destruction of insect contamination in food
and plants. My concentration has been on experiments
and modeling the interaction of the discharge with
the surface. In the experiments, probe techniques
and optical emission spectroscopy have been used
to estimate plasma parameters. A secondary interest
has been the study of dense low temperature plasmas
in electrothermal and electromagnetic launchers
and ablation stabilized arcs in general. I've concentrated
on measurements and interpretation of the spectral emission in the visible part of the spectrum. I have
been working on techniques for deducing plasma density
and temperature from the spectral emission as well as
the plasma current, input energy and ablated mass.
The spectral emission presents a special challenge due to
the multi-species molecular emission and absorption
and the plasma boundary as well as the greatly
pressure broadened atomic features in the core of the arc.
This research is also applicable to plasma opening
switches, high temperature plasma processing and fusion first
wall plasmas.
