A Langmuir probe is a device used to determine the electron temperature, electron density, and electric potential of a plasma. It works by inserting one or more electrodes into a plasma, with a constant or time-varying electric potential between the various electrodes or between them and the … See more The beginning of Langmuir probe theory is the I–V characteristic of the Debye sheath, that is, the current density flowing to a surface in a plasma as a function of the voltage drop across the sheath. The analysis presented … See more The Debye sheath theory explains the basic behavior of Langmuir probes, but is not complete. Merely inserting an object like a probe into a … See more Most often, the Langmuir probe is a small sized electrode inserted into a plasma which is connected to an external circuit that measures the … See more • Dual segmented Langmuir probe • List of plasma (physics) articles • Plasma parameters See more Once one has a theory of the I-V characteristic of an electrode, one can proceed to measure it and then fit the data with the theoretical … See more For laboratory and technical plasmas, the electrodes are most commonly tungsten or tantalum wires several thousandths of an inch thick, because … See more • Hopwood, J.
