Anomalous electron mobility in a coaxial Hall discharge plasma.
A comprehensive analysis of measurements supporting the presence of anomalous cross-field electron mobility in Hall plasma accelerators is presented. Nonintrusive laser-induced fluorescence measurements of neutral xenon and ionized xenon velocities, and various electrostatic probe diagnostic measurements are used to locally determine the effective electron Hall parameter inside the accelerator ...
متن کاملNonintrusive characterization of the azimuthal drift current in a coaxial ExB discharge plasma.
A diagnostic is developed for the nonintrusive study of the azimuthal drift current in the coaxial ExB discharge of a Hall plasma accelerator. The technique of fast current interruption is used to generate a signal on several loop antenna that circle the outer wall of the discharge channel. The signal on the antenna is recorded, and used to determine the spatial distribution of the azimuthal dr...
متن کاملExperimental Investigation of the Pulse and Plasma Flushing Efficiency in Electrical Discharge Machining
This paper presents a study of the relationship between Electrical Discharge Machining (EDM) parameters on the EDM efficiency factors using a full factorial design, based on pulse on-time, duty cycle and tool polarity parameters in EDM machining of AISI H13 tool steel. The results show that, in positive polarity, the plasma flushing efficiency and pulse efficiency increase according to the puls...
متن کاملTime and space-correlated plasma potential measurements in the near field of a coaxial Hall plasma discharge
Spaceand time-correlated measurements of floating and plasma potential are made in the near field, external flow cathode region of a coaxial Hall plasma discharge using an emissive probe synchronized to quasicoherent fluctuations in discharge current. The luminous axial feature frequently observed in the near field of operating plasma accelerators is found to be concomitant with a spike in the ...
متن کاملAlignment Efficiency of Superelastic Coaxial Nickel-Titanium
The preliminary phase of any orthodontic treatment with fixed appliances is the alignment and leveling of teeth. Leveling is the process in which the incisal edges of the anterior teeth and the buccal cusps of the posterior teeth are placed on an ideal horizontal level; and alignment is the lining up of teeth of an arch in order to achieve normal contact point relationship. In the alignment pha...
