On the Use of Sweeping Langmuir Probes in Cutting-Arc Plasmas—Part II: Interpretation of the Results

Abstract

A semiempirical Langmuir probe model is introduced 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 plateau in the ion branch of the current-voltage (I-V) probe characteristic, and the signal amplitude is independent of the probe radius… (More)
