Workshop on Oxygen Plasma Kinetics
September 19 - 20, 2016, Reykjavik, Iceland
Electrical discharges in oxygen-containing gases are ubiquitous in nature and in many man-made plasma applications (including low-pressure plasma processing and atmospheric pressure applications such as plasma medicine and pollution abatement). They are also an exemplar of electrical discharges in a simple molecular gas, showing all import phenomena such as dissociation, electronic (including metastable), vibrational and rotational excitation, and negative ion formation, providing an ideal test case for comparison of models with comprehensive diagnostic measurements. Nevertheless, many uncertainties persist concerning the collision cross-sections and rate constants necessary to make fully predictive models. These areas include:
Electron impact cross-sections for dissociation, vibrational excitation and electronic excitation
Role of metastable states (O2(a1), O2(b1) and, O(1D))
Negative ion creation and destruction mechanisms and rates (attachment and detachment processes)
Energy transfer processes controlling the different energy distribution functions (vibration, rotation, translation)
Surface processes including recombination, quenching, ozone formation and vibrational relaxation
The aim of this workshop is to unite researchers from the different communities working on different aspects of this system, including plasma modelling, plasma diagnostics, and the measurement and calculation of collision cross-sections and reaction rate coefficients, in order to pool our knowledge, define what we do and don’t know and identify the best strategies to determine the most important missing data.
The workshop on oxygen plasma kinetics 2016 will be held from Monday September 19, to Tuesday September 20, 2016, at the Radisson Blu Saga Hotel, Reykjavik, Iceland.
