“…When the injection continues at t = 4.55 µs, the electron density in the region closest to the cathode does not increase immediately at this time, and the side of the sheath away from the cathode gets closer and closer to the cathode, and the length of the sheath gradually becomes shorter. When the voltage spike ends, the electron density in the near-cathode region begins to recover to an order of magnitude above 10 17 .…”

“…When no new CS is generated, the process of supplying plasma from the cathode is interrupted instantaneously, which eventually leads to "ion starvation" in the anode region [15]. In addition, the research of Smeets and Kaneko [1] has combined experimental results to speculate that the extinction and reignition of the CS produces a space-charge layer similar to the postarc sheath, which moves toward the anode at a velocity close to the ion velocity (∼10 4 m/s) [16], [17].…”

“…Действительно, если катодное пятно представляет собой непрерывную смену взрывов и погасаний, то неизбежно настанет момент, когда катодные пятна погаснут одновременно, что приведет к погасанию всей дуги. Предыдущие исследования процесса спонтанного погасания показывали [17], что окончание дугового процесса -крайне быстрый процесс, который занимает несколько наносекунд. Этот процесс, как правило, сопровождается всплеском тока ионов [18], а также всплеском потока горячих электронов [19].…”
