A Langmuir probe is a device named after Nobel Prize winning physicist Irving Langmuir, 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. The measured currents and potentials in this system allow the determination of the physical properties of the plasma. 3, record 1, English, - Langmuir%20probe

La sonda de Langmuir es la forma más barata de hacer el diagnóstico de un plasma, es decir, determinar la temperatura y densidad de electrones, la función de distribución para los electrones, el voltaje del plasma, la frecuencia del plasma, la longitud de Debye y campos eléctricos en el plasma. Entre otras cosas la sonda de Langmuir también es excelente para determinar la presencia de inestabilidades e identificación de los varios tipos de éstas. 1, record 1, Spanish, - sonda%20de%20Langmuir
