An Interpretation of Langmuir Probe Floating Voltage Signals in a Cutting Arc.
(2009)
An experimental study of the electrostatic probe
floating voltage signals in a cutting arc and its physical interpre tation in terms of the arc plasma structure is reported. Sweeping
electrostatic probes have been used ...
On the Use of Sweeping Langmuir Probes in Cutting-Arc Plasmas—Part II: Interpretation of the Results.
(2008)
A semiempirical Langmuir probe model is intro duced that is particularly adapted to high-energy-density cutting
arcs, for which, as we have shown in Part I, the ion current
collected by negatively biased probes shows no ...
On the Use of Sweeping Langmuir Probes in Cutting Arc Plasmas—Part I: Experimental Results.
(2008)
The first study of Langmuir probes applied to cut ting arcs using a sweeping-probe system is presented. It is found
that, under a relatively broad range of experimental conditions
(changes in the probe material, in the ...
