Measuring Plasma Parameters With Thermal Noise Spectroscopy

Moncuquet, Michel; Issautier, Karine; Meyer-Vernet, Nicole +4 more

This paper describes the basic principles, the unique features and the limitations of thermal noise spectroscopy as a tool for in situ diagnostics in space plasmas. This technique is based on the analysis of the electrostatic field spectrum produced by the quasi-thermal fluctuations of the electrons and ions, which can be measured with a sensitive…
