Simulation of a Hall Effect Thruster Using Krypton Propellant

Autor: Alejandro Lopez Ortega, Iain D. Boyd, Hani Kamhawi, Horatiu C. Dragnea

Publikováno v: Journal of Propulsion and Power. 36:335-345

The multifluid computational framework Hall2De is updated to perform simulations of Hall thrusters operating with krypton propellant. The implementation is validated by comparison to past experimen...

Characterization of Eroded Boron Atoms in the Plume of a Hall Thruster

Autor: Azer P. Yalin, Brian Lee, Horatiu C. Dragnea, Iain D. Boyd

Publikováno v: IEEE Transactions on Plasma Science. 43:35-44

The erosion of boron particles from Hall thruster channel walls is a concern because it limits the lifetime of the device. A new optical experimental technique that measures path-integrated boron number density in the plume of a Hall effect thruster

On channel interactions in nested Hall thrusters

Autor: Sarah E. Cusson, Ethan T. Dale, Iain D. Boyd, Horatiu C. Dragnea, Marcel P. Georgin, Alec D. Gallimore, Vira Dhaliwal

Publikováno v: Journal of Applied Physics. 123:133303

Nested Hall thrusters use multiple, concentric discharge channels to increase thrust density. They have shown enhanced performance in multi-channel operation relative to the superposition of individual channels. The X2, a two-channel nested Hall thru
