Abstract: | Experimental data for a spark discharge in the tip-plane electrode configuration in argon are considered for the case when
the discharge current is limited by a high-resistivity ballast resistor. It is shown that the current passing in the thin
plasma channel of a low-current spark represents a steady sequence of regular pulses. It is found that low-frequency current
pulses of the low-current spark are accompanied with high-frequency current oscillations of nanosecond duration. |
