To match the observed thrust and discharge current in Hall thrusters, computer simulations have typically assumed anomalous electron transport mechanisms, such as Bohm diffusion, to enhance electron mobility across magnetic field lines. Without enhanced electron transport, the simulations predict a much lower discharge current than observed, and too ...

Genetic algorithm for ion thruster grid design
2007 16th IEEE International Pulsed Power Conference, 2007Summary form only given. A genetic algorithm was used to optimize ion thruster grid sets with regard to maximizing impulse per unit area, essentially equivalent to maximizing propellant throughput capability per unit area. Ion thrusters, while currently used for satellite station-keeping, are also valuable for performing deep space missions, such as ...
