Transition of MHD Kink-Stability Properties between Line-Tied and Non-Line-Tied Boundary Conditions (2008)

Sun, X, Intrator, T.P., Dorf, L, Furno, I, Lapenta, G

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 (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...
