Esgee to present at 71st GEC in Portland

October 30th, 2018 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 and […]


Now Import Chemistries from Quantemol QDB

October 17th, 2018 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 at info@esgeetech.com […]


Kinetic PIC Modeling of Ion Beam Neutralization

October 4th, 2018 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 […]
