Magnetic flux tubes or flux ropes in plasmas are important in nature and the laboratory. Axial boundary conditions strongly affect flux rope behavior, but this has never been systematically...
Current-Driven Rotating-Kink Mode in a Plasma Column with a Non-Line-Tied Free End (2008)
Furno, I., Intrator, T.P., Ryutov, D.D., Abbate, S., Madziwa-Nussinov, T., Light, A., ...
Current driven rotating kink mode in a plasma column with a non-line-tied free end (2006)
Furno, I., Intrator, T. P., Abbate, S., Madziwa-Nussinov, T., Light, A., Dorf, L., ...
First experimental measurements are presented for the kink instability in a linear plasma column which is insulated from an axial boundary by finite sheath resistivity. Instability threshold below...
Diagnostic Setup for Characterization of Near-Anode Processes in Hall Thrusters (2003)
Dorf, L., Raitses, Y., Fisch, N. J.
A diagnostic setup for characterization of near-anode processes in Hall-current plasma thrusters consisting of biased and emissive electrostatic probes, high-precision positioning system and...
Effect of Anode Dielectric Coating on Hall Thruster Operation (2003)
Dorf, L., Raitses, Y., Fisch, N. J., Semenov, V.
An interesting phenomenon observed in the near-anode region of a Hall thruster is that the anode fall changes from positive to negative upon removal of the dielectric coating, which is produced on...
The possibility of a Hall thruster operation in the absence of the anode sheath (2002)
Dorf, L., Semenov, V., Raitses, Y., Fisch, N. J.
A method of determining boundary conditions for quasi 1-D modeling of steady-state operation of a Hall Thruster with ceramic channel is presented. For a given mass flow rate and magnetic field...
