Abstract: The diagnostics of the ionospheric plasma by in-situ measurements of the lower-oblique resonance of a magnetized plasma is described. The electron density and temperature are derived from a nested set of resonance cones that is excited by a small antenna and detected by a movable receiver. Asymmetries of the resonance cones give access to electron drifts or electron beams. A detailed discussion of the hardware of resonance cone instruments is included.
Key words: Plasma parameters, drift velocity, lower oblique resonance.
