Modeling of double stage Hall effect thruster

IEEE Transactions on Plasma Science, 2005
Hall effect thrusters (HETs) are ion sources used for satellite station keeping and orbit raising. In Single Stage HETs, the same electric field is responsible for electron heating and ion acceleration. We present a new HET concept where ionization and acceleration are separated in two different stages. This double stage HET allows for a more versatile

The Effects of Background Pressure on Hall Thruster Operation

48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012
Performance, plume properties, and discharge stability of a 9 cm diameter laboratory model Hall thruster were measured at vacuum chamber background pressures ranging from 1e-6 to 6e-5 Torr. The thruster was operated at constant discharge powers of 300 and 500 W while background pressure was varied from the minimum achievable value to values 10, 20, and

Effect of the Discharge Voltage on the Performance of the Hall Thruster

Plasma Science and Technology, 2016
In this paper, a two-dimensional physical model is established according to the discharging process in the Hall thruster discharge channel using the particle-in-cell method. The influences of discharge voltage on the distributions of potential, ion radial flow, and discharge current are investigated in a fixed magnetic field configuration.

Electron and Ion in Hall Effect Thrusters

2008
Hall Effect Thrusters (HETs) are gridless ion sources that can provide thrust on the order of 80 mN per kW of electrical power, with propellant velocity in the 20-30 km/s range. HETs are well suited for tasks such as satellite station keeping and are also considered for interplanetary missions.
