WAVE PROBE LEMI-603

WAVE PROBE LEMI-603

Wave probe LEMI-603 is a combined instrument intended for simultaneous measurements of magnetic field, electric current density and electric potential fluctuations in ionospheric plasma. It is the combination of search-coil magnetometer and split Langmuir probe in one body. The simultaneous measurements of orthogonal components of spatial current and magnetic field fluctuations allows to obtain immediately the estimation of wave vector k in the plane wave approach.
