Volt-Ampere characteristics of a cylindrical probe in the ionosphere plasma irregularities regions
Abstract
Cylindrical Langmuir probes are widely used for measurements of ionosphere plasma density and temperature. But a great deal of experimental data for such probe measurements fulfilled abroad "ICBulgaria-1300" satellite showed that Langmuir probe Volt-Ampere (V-A) characteristics with extraordinary forms were frequently observed. In this report it is shown that thanks to uneven distributions of plasma parameters inside irregularities, the Langmuir probe's V-A characteristics whose execution time period happened to be close to those time intervals which were necessary for the satellite to pass through such irregularities, are subjected to some characteristic distortions. Also possible ways to originate these irregular structures will be discussed and it will be shown that sources for these structures can be situated in the magnetosphere or in the ionosphere.
