With the sheath edge defined, as in the Child-Langmuir law, at the place where the ion velocity is equal to the Bohm velocity, the sheath thickness of a bounded collisionless or weakly collisional plasma has been found with this model in some cases to be much larger than that obtained ...
This is the reason why many authors came up with various models of the plasma sheath where the most popular one is the model of the sheath as a cylindrical vacuum region around the dipole and the plasma is assumed to be homogeneous up to the surface of the sheath, studied in detail by ...
Instead, a collisional radiative model must be used. Modeling collisional radiative processes are essential for transport modeling both in the edge and core of fusion plasma. Collisional radiative processes also play a large role in modeling plasma material interactions. The important role of atomic ...
摘要: The sheath criterion in a collisional plasma sheath is investigated with a two-fluid model. It is shown that if neutral-ion collisionality in the sheath is taken into account, uppe... 查看全部>>关键词: Patch active plasma Bohm criterion Electronegative gases Model Transition ...
A triple frequency capacitively coupled plasma(TF-CCP) has been considered to investigate the behavior of the sheath parameters.A self-consistent time-independent collisionless model has been developed.The sheath width and potential are calculated using the present model and compared with those calculated...

Two-temperature electronsPlasma sheathCollision effectSagdeev potentialA constant mean free path collisional plasma sheath model is investigated in the presence of two-temperature q-nonextensive electrons and fluid ions. By using Sagdeev potential technique, a modified......
Collisional plasma sheathMagnetic fieldIon dynamicsUsing the fluid model, we investigated the velocity, kinetic energy and the density distribution of the ions in collisional and collisionless magnetized plasma sheath. Considering an external magnetic field, the ion movement under the effect of magnetic,...
