Circuit Details and Application Note for a Versatile Plasma Probe

Abstract

A plasma-probe circuit has been developed which couples standard Langmuir-probe diagnostic procedures with pulse-mode operation. Circuit versatility provides the means for studying time-dependent phenomena and establishes an improved capability for measuring plasma density and temperature. As an application of the circuit, it is shown that pulse-mode operation reduces the time variance of electrode surface conditions which often cause hysteresis in the Langmuir-probe current-voltage characteristic.
