The Plasma Analyser measures the plasma parameters, including ion density, ion temperature, ion drift velocity, ion composition and ion density fluctuation, for searching:
- the coupling between ionosphere and seism
- the ionospheric physics
The PAP payload, shown in Figure, consists of three different ion analyzers (ion capture meter, retarding potential analyser, ion drift meter), mechanically fixed on a conducting plate. The Plasma Analyzer has been tested in the INAF-IAPS Plasma Chamber.
