Measurement of the Current-Voltage Characteristics of Argon Plasma with a Tracking Probe

详细

The current-voltage characteristics of argon plasma are investigated in the presence of noise using a tracking probe. It is revealed that at too close arrangement of the reference and measuring probes, the layer adjacent to the measuring probe influences differently the reference probe in different sections of the characteristic. For this reason, the number of triggering pulses changes during measurements of the current-voltage characteristics; therefore, the pulses should be counted when measuring the entire characteristic. Sequential ordering of the number of pulses per unit time demonstrates that probes insignificantly affect each other.
