On the magnetic mirror effect in Hall thrusters [PDF]
Applied Physics Letters, 2005 The magnetic mirror effect is studied in the channel of a Hall thruster. It is shown that gradients in magnetic field affect the presheath structure and electric potential distribution. The length of the radial presheath region decreases in the presence of a magnetic field gradient.

Mode Transitions in Hall Effect Thrusters [PDF]
49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013 Mode transitions have been commonly observed in Hall Effect Thruster (HET) operation where a small change in a thruster operating parameter such as discharge voltage, magnetic field or mass flow rate causes the thruster discharge current mean value and oscillation amplitude to increase significantly.
