helical resonator plasma simulation

Esgee Technologies will be attending the 71st Annual Gaseous Electronics Conference in Portland, Oregon next week, November 5 – 9. Join Esgee Tech’s Rochan Upadhyay for his talk on “Computational Modeling and Simulation of a Resonant Plasma Source.” He’ll demonstrate how electrical resonance can be exploited to extend low temperature, unmagnetized plasma sources beyond their typical operating limits. Esgee also supported the work being presented by Tokyo Electron America’s Peter Ventzek. He will present “Parametric Modeling

OverViz QDB plasma chemistry

Quantemol’s QDB plasma chemistry library now supports the OverViz chemistry format. Simply export a chemistry from QDB in the OverViz format (includes both gas and surface chemistries), then load them directly into any of the OverViz modules for plasma simulation. OverViz users now have even more flexibility in defining complex chemistries for simulation, whether loading from VizData, importing from QDB, or creating their own. QDB membership required for QDB chemistry access. Contact us

PIC beam neutralization

Ion beam neutralization is a significant challenge in electric propulsion and is needed to reduce beam electric fields, manage space charge, and reduce ion sputter of the spacecraft. To address these challenges, simulation can be used to investigate ion/electron interactions, predict space charge distributions, and optimize system properties, such as cathode location, beamlet current, ion density, and electron temperature. However, beam neutralization can be a challenging problem to simulate due to the extreme difference in

ChemZone Plasma Simulation

Our flagship product, VizGlow, is a powerful, multi-dimensional software tool for simulating industrial, non-equilibrium plasmas. VizGlow can resolve spatial and time accurate plasma discharges with complex reactor geometries in three dimensions using a parallel simulation framework. While it is extremely robust, it is not always the best place to start when implementing a new chemistry mechanism or optimizing a plasma process. For these types of problems, we recommend starting with ChemZone. ChemZone is a fast,

Satellite charge-up simulation

Esgee will present “High-fidelity Multi-Length Scale Modeling of Spacecraft Charging in GEO orbit” at the 15th Spacecraft Charging Technology Symposium 25-29 June, 2018 at the Integrated Research Center of Kobe University in Japan.   Abstract This study describes high-fidelity modeling of spacecraft charging in GEO orbit environment and the resulting incipient vacuum arcing on the spacecraft’s surface. A satellite in GEO environment is subject to continuous bombardment by highly energetic charged particles that accumulate over
