摘要
It is shown via computer simulations that a protrusion 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 geometry of the cathode and may play a role in operation of electrodes of compact high-intensity discharge lamps.
