“…An increase in the beam current was observed, as expected, with an increase in the initial concentration of the anode plasma, which is illustrated by the waveforms shown in Figure 4. It can be seen that with an increase in the delay time τ d from 15 to 35 µs, the average value of the beam current in the first half of the pulse (with a duration of about 1 µs) decreases approximately three times, which corresponds to the results of measurements of the ion density in the plasma anode obtained by us earlier using double probes (Figure 5) [16].…”

“…Видно, что с ростом времени задержки τ d с 15 до 35 µs среднее значение тока пучка в первой половине импульса (длительностью около 1 µs) уменьшается примерно в три раза, что соответствует результатам измерений концентрации ионов в плазмен-a c b a c ном аноде, полученным нами ранее с помощью двойных зондов (рис. 5) [16]. Следует также отметить, что при больших временах задержки (τ d > 35 µs), существенно возрастала нестабильность токов катода и пучка от импульса к импульсу, что, вероятно, обусловлено низкой концентрацией анодной плазмы, а, следовательно, ухудшением условий для образования взрывоэмиссионных центров на катоде и устойчивости транспортировки пучка к коллектору.…”
