Time resolved spectroscopy of an underwater dielectric barrier discharge plasma jet

Summary form only given. Atmospheric pressure plasmas in liquid water have enjoyed much attention recently due to their ability to create vast quantities of short-lived radicals, excited species, and many other highly oxidative particles that have the ability to sterilize contaminated water. These plasmas have been shown to exhibit several distinct characteristics over a power cycle. The varying physical differences are believed to correspond to significant changes in the production mechanics of important chemical species. The dynamic characteristics of these plasmas require dynamic analyses. Presented here are the results of time-resolved spectroscopy of an underwater dielectric barrier discharge plasma jet.
