FIG. 1.

Schematic of the coaxial plasma source.

FIG. 2.

Example of FFT of voltage data for a 50 A titanium arc, captured with different time resolution at the oscilloscope , where each division has 50 data points.

Image of FIG. 3.
FIG. 3.

FFT curves (average of 16 amplitude vs frequency measurements) for two extreme materials, Bi and W. For comparison, the same FFT procedure was also applied to the voltage zero line (i.e., no arc burning).

Image of FIG. 4.
FIG. 4.

Amplitude difference between FFT curves of arc voltage and FFT of the voltage zero line, measured at 40 MHz plotted vs the cohesive energy of the cathode material.
