Effect of protrusions on cathodic-arc-attachment mode in high-pressure arc discharges. IEEE transactions on plasma science, 36(4), 1034-1035. DOI: 10.1109/TPS.2008.920888http://hdl.handle.net/10400.13/4528It is shown via computer simulations that a protru sion on a thermionic arc cathode may dramatically change the pattern of steady-state modes of current transfer. This happens through a bifurcation of a special type occurring at certain geom etry of the cathode and may play a role in operation of electrodes of compact high-intensity discharge lamps.engArc attachmentArc cathodeBifurcation of current transferBifurcation theoryHigh-pressure arc..Faculdade de Ciências Exatas e da Engenhariajournal article10.1109/TPS.2008.920888
