Microcathode Thruster (\mu\hbox) Plume Characterization

An experimental observation of microcathode thruster plasma plume is described. An effect of the magnetic field on the plume expansion is considered. Two observation techniques are employed--charge-coupled-device camera and the concentric Langmuir probe. It is found that magnetic field significantly...

Description
Summary:An experimental observation of microcathode thruster plasma plume is described. An effect of the magnetic field on the plume expansion is considered. Two observation techniques are employed--charge-coupled-device camera and the concentric Langmuir probe. It is found that magnetic field significantly affects the plasma plume, and the strong magnetic field can lead to hollow plume formation.
