Current fluctuations of cathodic arcs were recorded with high analog bandwidth (up to 1 GHz) and fast digital sampling (up to 5 Gsamples/sec). The power spectral density of the arc current was determined by fast Fourier transform clearly showing material dependent, non-linear features in the frequency domain. These features can be associated with the non-linear impedance of the conducting channel between cathode and anode, driven by the explosive nature of electron emission and plasma formation… CONTINUE READING
