Measurement of Electron Density and Temperature by Means of Contamination-Free Probe
Antarctic Record, 1975 In plasma diagnosis by means of a Langmuir probe, contamination of the electrode is a quite serious problem. In order to get reliable data of space plasma, cleaning of the electrode is an essential requirement.

Designs of Langmuir probes for W7-X [PDF]
Fusion Engineering and Design, 2011 Abstract Several designs of Langmuir probes for the stellarator Wendelstein 7-X (W7-X) are described. Different types of probes are proposed for the different divertors to be used during different operational phases of W7-X. Comb-like arrays of stiff probes, arrays of flexible probes, and fixed inlay probes are reviewed. For the initial phase of W7-X

The effect of surface contamination of tiny satellite on DC probe ionosphere measurement
AIP Advances, 2018 The DC Langmuir probe is a widely-used instrument for the plasma measurement in the space missions. But to apply DC Langmuir probe to a tiny satellite, such as a cubesat, for ionosphere study is difficult to get accurate electron density (ne) and ...
