LXCat is an open-access platform () for curating data needed for modeling the electron and ion components of technological plasmas. The data types presently supported on LXCat are scattering cross sections and swarm/transport parameters, ion-neutral interaction potentials, and optical oscillator strengths. Twenty-four databases contributed by different groups around the world can be accessed on LXCat. New contributors are welcome; the database contributors retain ownership and are responsible for the contents and maintenance of the individual databases. This article summarizes the present status of the project. [ABSTRACT FROM AUTHOR]

One of the factors limiting the lifetime of plasma display panels (PDPs) is sputtering of the MgO layer deposited on the dielectric covering the electrode. The goal of the work reported here is to evaluate the influence of different operating conditions on the sputtering rate of the MgO layer in PDPs operating with Xe/Ne mixtures. Sputtering is caused by the ions and fast neutral atoms impacting the surface. Starting with results from a fluid model, we use a Monte Carlo simulation to calculate energy distributions of the ion and fast neutrals arriving on the MgO coated surface for a set of baseline conditions. Estimates of the sputtering yield of MgO are then combined with the energy distributions to evaluate the sputtering rates for matrix and coplanar geometries. Parametric calculations in a simple geometry were performed to examine the effect of gas mixture, gas pressure, cell capacitance, and applied voltage on the sputtering rate of the MgO layer. Our main result is the prediction of longer lifetime for mixtures containing about 20%Xe for both matrix and coplanar geometries. [ABSTRACT FROM PUBLISHER]

Microplasma jets propagating in a helium flow surrounded by open air at ambient temperature have attracted the attention of many researchers for their putative ability to deliver high fluxes of reactive oxygen and nitrogen species to a target situated some centimeters away. This is of particular interest in biomedical applications. In this paper, we use Schlieren images to show that ignition of the plasma jet causes a reduction in the length of the laminar zone of the helium flow. [ABSTRACT FROM PUBLISHER]
