Anomalous electron transport in magnetized low-temperature plasmas
This text mentions work from 2024 on. Those parts were partly written without a live literature search and have not been checked by an editor yet.
Hall thrusters (spacecraft engines that push ions with an electric field across a magnetic field) rely on the magnetic field to hold electrons back, but electrons cross it far faster than collisions allow. Without knowing why, these engines cannot be designed from first principles.
Why it matters
Predictive design of electric propulsion, magnetron sputtering sources and Penning discharges needs a validated model of cross-field electron transport.
