Abstract:

The University of Missouri-Columbia UM-C has developed pulsed ultraviolet UV photon sources commensurate with enhanced ultraviolet inactivation of hazardous microbials on surfaces or in a water matrix. Pulsed xenon flashlamps have been optimized to produce a high ultraviolet photon yield in the 180 320 nm range that is lethal to microbials and has a high cross-section interaction with photosensitizer chemicals to synergistically enhance microbial inactivation. Electrical models have been derived to predict the time dependent plasma discharge impedance profiles of the flashlamp UV source. These models are discussed in the following paper.
