Download or read book Kinetic Theory Solution for the Spherical Electrostatic Probe in a Stationary Plasma written by Yon-Sun Chou and published by . This book was released on 1966 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spherical electrostatic probe immersed in an infinite weakly ionized gas is studied from the kinetic theory point of view. The Boltzmann equations are transformed into an energy-angular momentum phase space. The charged particle motion is fully analyzed in this phase space. By using a Krook-type model for charged-neutral particle collision, a formal integral solution of the distribution function is discussed. Lees' moment equations are derived, and sample solutions for those moment equations are computed. From the sample solutions it is found that (1) The sheath effect is much more pronounced for a positive potential probe than a negative one. (2) On decreasing the ratio of Debye length to probe radius the ion current is decreased, the sheath effect is more pronounced, and the saturation ion current is reached at smaller negative probe potential. (3) The effect of collisions is to help the plasma to sustain more potential, to decrease both the ion current and electron current, as well as to reduce the excess ion number density in the sheath region. (4) In the collisionless case, when the ion temperature is increased the ion current is also increased. This increase becomes negligibly small at large negative probe potentials.

Available in PDF, EPUB and Kindle. Book excerpt: Il libro copre argomenti fondamentali nella fisica dei plasmi quali onde nei plasmi, instabilità e processi non lineari. Dopo una approfondita descrizione teorica vengono anche evidenziate osservazioni da satelliti di questi fenomeni in plasmi spaziali quali la ionosfera terrestre, la magnetosfera e il vento solare. L’ultima parte del libro tratta le interazioni di corpi carichi con un plasma. Nel caso di misure da satellite abbiamo a che fare con un campo magnetico esterno e col moto del satellite nel plasma, Non essendoci una teoria esatta in queste circostante vengono usati metodi approssimati che tuttavia conducono a delle stime credibili della corrente raccolta. Anche per questi argomenti le teorie presentate sono raffrontate a misure di satellite e in particolare ai risultati della missione TSS (Tethered Satellite System).
