The Plasma Pulse

Mastering Instabilities and Erosion in Hall Effect Thrusters

The silent flicker of a Hall thruster is the difference between a successful mission and a catastrophic failure.

Strategic Objectives

• Decode the complex physics of crossed-field ionized gas behavior.

• Identify and mitigate the 'breathing mode' and other disruptive oscillations.

• Extend thruster lifespan by understanding plasma-wall interaction dynamics.

• Master the predictive modeling of E-field induced erosion patterns.

The Core Challenge

Deep-space propulsion faces a critical bottleneck: the chaotic plasma instabilities and relentless wall erosion that degrade Hall Effect Thrusters.
