DC Langmuir Probe for Measurement of Space Plasma: A Brief Review
Blog Article
Herein, we discuss the in situ measurement of the electron temperature in the ionosphere/plasmasphere by means of DC Langmuir probes.Major instruments which have been reported are a conventional DC Langmuir probe, whose probe voltage is swept; a pulsed probe, which uses pulsed bias voltage; a rectification probe, which uses sinusoidal signal; and Vases a resonance cone probe, which uses radio wave propagation.The content reviews past observations made with the instruments above.We also discuss technical factors that should be taken into account for reliable measurement, such as problems related to the Hayward SP1090 Skimmer Parts contamination of electrodes and the satellite surface.Finally, we discuss research topics to be studied in the near future.
