Langmuir probe for measuring the electron concentration of the Earth's ionosphere D-layer at altitudes from 60 to 90 km

摘要

The utility model relates to the field of geophysics and meteorology, namely to the field of electric probe designs for measuring the electron concentration of the Earth’s ionosphere in the D-layer region (60-90 km) using parachutes delivered to a given height by small meteorological rockets. The Langmuir probe for measuring the electronic concentration of the Earth's ionosphere D-layer at altitudes of 60 to 90 km contains a measuring metal electrode (1), a reference electrode (2) (counter-probe), a power source (3), a sawtooth voltage generator (4) to create potential between the electrodes, and the reference electrode (2) is made in the form of a dome of a parachute in the form of a hemisphere, while the ratio of the area S of the dome of the parachute (reference electrode) to the area S of the measuring electrode is in the range from 10 to 1.2 10, and the measuring electrode (1) is fixedod parachute canopy (2) on its axis at a distance L, of 1.0 to 1.5 m from the lower edge of the dome. EFFECT: increased reliability and accuracy of measurements of electron concentration in a given region of the Earth's ionosphere. 3 s.p. f-ly, 4 ill.
