“…These theories are suitable when the temperature of the positive ions is negligible compared to the electron temperature [4,5,[11][12][13][14][15][16][17][18] and are normally known as Allen-Boyd-Reynolds (ABR) models. In recent years, the study of the interaction of the plasma with a spherical body has also become a point of interest due to its application to dusty plasmas and the study of crystal plasmas [19][20][21][22].…”

This paper solves and analyses the complete characterization of the plasma-sheath transition and the characteristic I-V curves of an active and collisional plasma close to a cylindrical or spherical wall considering a wide range of the parameter which describe the model to be useful for experimental measures. Despite the difficulty of including the three possible presheath mechanisms, this characterization is obtained from a self-consistent model using three easily measurable parameters, namely the electric potential of the wall, the positive ion current collected by the wall, and the radius of the wall. These parameters are easy to measure and facilitate the diagnosis of plasmas from an experimental point of view.

“…Distributions of electric potential, ion and electron densities depend on the lattice structure of a dusty crystal. At present, dusty crystals are very actively investigated (see [1]), but earlier there were no models describing the external electric field and non-spherical symmetry.…”
