In the last 30 years, numerical models have revealed different physical mechanisms
involved in the Hall thruster functioning leading to a bridge between analytical …

For several decades, Hall-effect thrusters (HETs) are being used in several applications,
such as orbiting satellites, deep space missions, etc. This article studies the effect of several …

Particle-in-cell methods are used for ions and neutrals. Probabilistic methods are
implemented for ionization, charge-exchange collisions, gas injection, and particle-wall …

A paradigm for Hall discharge modeling is presented whereby only the time scale of the
lowest-frequency mode is explicitly resolved. The ability of such a low-frequency model to …

The interaction of the plasma discharge with the ceramic walls of a Hall thruster leads to
plasma recombination, energy losses, and extra electron collisionality. These three …

Electron-wall interaction effects in Hall thrusters are studied through measurements of the
plasma response to variations of the thruster channel width and the discharge voltage. The …

A bounded plasma where the hot electrons impacting the walls produce more than one
secondary on average is studied via particle-in-cell simulation. It is found that no classical …

During the early development stages of Hall thruster technology, plasma research and
propulsion advancements centered primarily on 300-V, 1600-s specific impulse operation …

A condition for sheath instability due to secondary electron emission (SEE) is derived for low
collisionality plasmas. When the SEE coefficient of the electrons bordering the depleted loss …

STANDARDIZATION of experimental methods, facilities, diag-nostic apparatus, and
efficiency analysis has previously been proposed in the electric propulsion community [1] …
