The Hall Thruster Experiment

The Hall Thruster Experiment (HTX) was established in 1999. The research objectives of the HTX are:

• Control of spatial distribution of plasma parameters in order to reduce beam divergence in the thruster channel and plume.
• Scaling of Hall thrusters to low (tens W) and high power (tens kW) levels.
• Understanding of physics involved in operation of Hall thrusters and crossed field plasma devices in general:
• Electron transport across magnetic field
• Plasma-wall interactions
• Plasma instabilities and their control
• Limitations of magnetic insulation in plasmas with magnetized electrons and non-magnetized ions.
• Interaction of high flux plasma jets with different targets (magnetic field, plasma and solid).
• Exploring of new configurations of crossed field plasma devices for space, scientific and industrial applications.
• Study of steady state electrical discharge in crossed field devices under various pressures and gases.
• Measurements of secondary electron emission properties of dielectric materials in low electron energy range (<1 keV).
• Applications of ferro-electric materials for efficient ionization and control of plasma-wall interaction in plasma sources.
