The gas supplied to the chamber through this system is weakly ionized; it is admitted from the chamber to the hollow cathode through the emissive grid of the source. As a result, the chamber and the hollow cathode are filled with low-density plasma. When the discharge power supply and the...
(made of copper) are 60 and 50 mm, respectively.A DC power supply (HSPY-1500-002)is connected to the cathode to provide a DC voltage up to 600 V.The distance between the two electrodes is L=130 mm.A 5 mm wide gap is reserved in the middle of the anode plate.Through the gap, ...
According to observations, the constriction starts near one of the electrodes and then the constricted region boundary propagates towards the other electrode. For the Ar:N2 mixture, the transition time is considerably longer than in pure argon. By proper variation of power supply voltage during the...
