Modeling of Neutral Entrainment in an FRC Thruster

reportActive / Technical Report | Accession Number: ADA586849 | Open PDF

Abstract:

Neutral entrainment in a field reversed configuration thruster is modeled numerically with an implicit PIC code extended to include thermal and chemical interactions between plasma and neutral particles. The contribution of charge exchange and electron impact ionization reactions is analyzed, and the sensitivity of the entrainment efficiency to the plasmoid translation velocity and neutral density is evaluated.
