High-Power Operation

Magnetically-shielded Hall thrusters are now state-of-the-art, potentially allowing for much higher current densities. How does the performance change at these previously-unexplored operating regimes? How can we push these power limits even further?

Krypton Performance

Krypton offers a cheaper and more readily available alternative to xenon as a propellant for Hall thrusters for low-thrust, high-Isp operation. Why is its efficiency so much lower than xenon's? How do we improve its performance and overcome its design challenges?
