Probe Methods of Studying the Ionosphere,
Abstract
Probing is the main technique used for investigating the gas-discharge plasma (comparatively cold plasma with a rather low concentration and weak magnetic fields). Characteristics obtained from probing (dependences of probe current upon voltage applied to a probe) may, in the main, be used for determining all the basic parameters of plasma, such as: electron and ion concentration, distribution of ions and electrons according to their energies and plasma potential in the area of the probe. Measurements carried out by means of probing allow the local parameters of the ionospheric plasma to be determined, the results of such measurements being independent of the condition of the medium between the probing means and the Earth. In principle this advantage of measurements carried out by means of probing allow, their utilization at any altitude. However, apart from difficulties encountered in the gas-discharge plasma, a number of difficulties which pertain particularly to the ionosphere may arise during measurements by means of probing.
