An in situ instrument that measures currents and potentials in the system formed by the carrier satellite and electrode(s) placed in the ambient plasma in order to infer plasma characteristics such as density and temperature
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. The measured currents and potentials in this system allow the determination of the physical properties of the plasma.
