Partially-magnetized E×B plasmas, where electrons are magnetized but ions are not, are key to technologies like Hall thrusters and ion sources for neutral beam injection for fusion. These plasmas host electrostatic instabilities (e.g., gradient-drift, lower-hybrid, electron cyclotron drift, modified two-stream) that can lead to wave turbulence. This project aims to study wave turbulence-driven transport with a pseudo-spectral solver. The focus is on understanding large-scale structure formation and the impact of parameters like gradients and boundaries. Results will be validated against kinetic simulations and will be used to assess the impact of the turbulent transport into macroscopic quantities as compared to experiments of electric propulsion thrusters.
