Langmuir probe - Wikipedia
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 surrounding vessel.

朗缪尔探针是指把一根除了端点工作部分以外其余部分均用绝缘材料覆盖的细金属丝插入等离子体内部，使其端点工作部分与等离子体接触，而另一端通过一可调电源与产生等离子体的电极相连,改变这金属丝对等离子体的电位,按照带电粒子在拒斥场作用下的 ...
The Langmuir probe is a diagnostic device used to determine several basic properties of plasma. 2, such as temperature and density. P lasma is the most prevalent form of ordinary matter. Plasma is a state of matter which contains enough free (not bound to an atom) charged particles (electrons and ions) so that its dynamical
In this short review is introduced the elementary theory of collecting Langmuir probes in spherical and cylindrical geometries. The classical results for either repelled and at-
On the other hand, the most widespread use of Langmuir probes at present is in the semiconductor industry, where radiofrequency (rf) sources are used to produce plasmas for etching and deposition. These partially ion-ized plasmas require special techniques in probe construction and theory.
Langmuir Probe - ESA
The Langmuir Probe (LMP) is an onboard scientific instrument of the satellite, its objective is to determine the parameters of the plasma in the upper regions of the Earth’s atmosphere (i.e., ionosphere). Investigating plasma anomalies and the effects of geomagnetic disturbances on space and Earth weather.
I give several simple examples of model Langmuir probe current-voltage I-V characteristics that help students learn how to interpret real I-V characteristics obtained in a plasma. Students can also create their own Langmuir probe I-V characteristics using a program with the plasma density,
A Langmuir probe consists of a bare wire or metal disk, which is inserted into a plasma and electrically biased with respect to a reference electrode to collect electron and/or positive ion currents.
