ASST. PROF. DR. VASCO GUERRA
Asst. Prof. Dr. Vasco Guerra from IST Lisboa, Portugal, will visit Dr. Efe Kemaneci from TET on September 3rd. His talk about "Kinetic modelling of microwave discharges in O2-containing mixtures" is at 11:00 am (ID 04/413).
Everybody interested is welcome to join!
Abstract: A self-consistent kinetic model is developed in order to study the elementary processes occurring in surfacewave microwave discharges in pure O2 and in the mixtures O2-Ar, O2-N2 and O2-N2-Ar. The theoretical formulation is based on the solution of a system of 0-D rate balance equations for the dominant neutral and charged species, coupled to the homogeneous electron
Boltzmann equation and to the quasi-neutrality condition, allowing the self-consistent determination of the sustaining reduced electric field E/N. The model is used to investigate different phenomena, such as dissociation in O2 discharges, production of O2(a) and UV emitting species, or the formation of NO and O3 molecules. The extension of the model to situations of
small-diameters / low-pressures, where the kinetics is strongly dominated by electron-impact collisions and wall interactions, is briefly discussed.
