37th AIAA Plasmadynamics and Lasers Conference, 2006
The cylindrical Hall thruster, proposed and studied at the PPPL features high ionization efficiency, quiet operation, ion acceleration in a large volume-to-surface ratio channel, and performance comparable with the state-of-the-art Hall thrusters. These characteristics were demonstrated in low and medium power ranges.

Propellant utilization in Hall thrusters
32nd Joint Propulsion Conference and Exhibit, 1996Fuel optimal trajectories for electrically propelled spacecraft require a varying thrust acceleration. To achieve this requirement the electric thruster has to be operated with a variable thrust to power ratio at the maximum available input power. In order to implement this operating mode with a Hall thruster it is necessary to modify both the mass ...

Rayleigh Instability in Hall Thrusters
38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002Gradient-driven Rayleigh-type instabilities in Hall plasma thrusters are analyzed using linearized two-fluid hydrodynamic equations. Necessary instability conditions and a general criterion for stability of azimuthally propagating perturbations are derived.

Conducting Wall Hall Thrusters
49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013A unique configuration of the magnetic field and channel geometry near the wall of Hall thrusters, called magnetic shielding, has recently demonstrated the ability to significantly reduce the erosion of the boron nitride (BN) walls and extend the life of Hall thrusters by orders of magnitude.

34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 1998
The acceleration of the plasma in the Hall thruster to supersonic velocities is examined by the use of a steady state model. Flows that are smooth across the sonic transition plane are found. The possibility of generating flows in which the acceleration across the sonic plane is abrupt, is also studied.

Journal of Propulsion and Power, 2013
The area of application of the Hall effect thrusters is constantly expanding, both in the direction of reduced power and toward an increase of power and specific impulse. The two main problems are studied in this paper. The first is to examine the possibility of providing the similarity of plasma parameters in Hall effect thrusters, and the second is ...

AIP Conference Proceedings, 1995
An improved design of the Hall type stationary plasma thruster has been tested in 1994. The test results are presented. The test measures performance, EMI and beam divergence of two models of thrusters from the Russian Keldysh Scientific‐Research Institute of Thermal Processes.

Segmented Electrode Hall Thruster
Journal of Propulsion and Power, 2006Thrust, thrust efficiency, and plume divergence were measured for a 9 cm diam laboratory model Hall thruster with segmented electrodes in the discharge channel. Several geometries with graphite nonemissive electrodes, and one with a tungsten emissive electrode were tested and compared to a baseline configuration with all electrodes replaced by boron ...
