PLASMA ELECTRON HEATING BY ABSORPTION OF COLD ELECTRONS
The electron temperature of a quiescent plasma in a metal discharge chamber, where the walls serve as the anode, can be raised by introducing a second anode consisting of 0.0025‐cm‐diam tungstenExpand

WILDCAT chemical sensor development
The WILDCAT sensor was developed to provide chemical detection and identification at large standoff ranges on the order of 20 km for concentration-path length product measurements and 5 km forExpand

Chemical detection on surfaces by hyperspectral imaging
TLDR
We have developed a method for using hyperspectral data to identify and locate chemical materials on arbitrary surfaces using the materials’ reflection or emission spectra that makes no prior modeling assumptions about the presence of pure pixels or the statistics of the background clutter and sensor noise.

Wavelength agile CO2 laser for chemical sensing
A compact, wavelength agile laser and sensor have been developed for remote detection of chemicals. The laser is a computer- controlled, sealed TEA CO2 device with internal catalyst that operates atExpand

Theoretical analysis of the electrically excited KrF laser
The results obtained from a comprehensive theoretical model for an electrically excited laser are compared with experimental data obtained from a large‐volume KrF laser device, excited by an e−‐beamExpand

CO2 laser excited by preionized transverse discharge through a dielectric
The effect of preionization on a dielectric‐electrode discharge in CO2 laser media is described. Compared to previous devices without preionization, specific energy extraction has been increasedExpand

Detecting liquid contamination on surfaces using hyperspectral imaging data
Over the past two years we have developed a new approach for detecting and identifying the presence of liquid chemical contamination on surfaces using hyperspectral imaging data. This work requiresExpand
