Abstract

We present the optimization of a sterilization process with a N2 flowing afterglow post-discharge. First we study the inactivation of bacteria (E. coli) submitted to the post-discharge, and discuss the mechanisms of bacteria inactivation. Then we evaluate the volume repartition of the active species (N atoms produced by plasma discharge) in the chamber of treatment.
