“…Existing systems created on the basis of pulsed arc discharges have a number of significant drawbacks, in particular, the low energy of the ions that heat the microdroplets. In previous direct experiments [1][2][3][4] it was established that the use of a pulsed discharge plasma with a hollow cathode (HC) allows several times reducing the number of Ti microdroplets with a size of ≈ (0.1…0.6) μm.…”

Peculiarities of the time dependence of the plasma parameters of a pulsed discharge with a hollow cathode in low-pressure argon were experimentally determined when using two types of pulsed high-voltage power sources – voltage and current sources (pulse duration up to 10 ms, voltage up to 10 kV). It is shown that the use of pulsed current sources provides significantly more stable discharge glow in the working range of argon pressure variations (2.5…10)10-4 Torr. At the same time, the temperature of plasma electrons of the discharge which was powered by a voltage source, was several times higher and could reach 40 eV.
