Plasma diagnostic by probes: study aid

Scientific basis of low-temperature plasma probe diagnostics is described in the textbook. Overview of probe methods of plasma diagnostics and a wide range of issues in their practical use is shown. Theoretical study of these methods, detailed description of the design features and the necessary formulas are given. Estimates of possible errors are made, a variety of tests are described. Using the Langmuir probe allows to obtain reliable data on the concentration of free electrons with high spatial and temporal resolution and to obtain estimates of the ratio of the concentrations of negative ions and free electrons in the plasma.
