摘要：
A new one-dimensional analytical model describing the diffusion of low-pressure electronegative plasma in homogeneous magnetic field is developed. The conditions are found when the electron diffusion becomes independent of ion diffusion, while the diffusion of the ion component depends on the electron diffusion. The model demonstrates the influence of various parameters such as power, magnetic field and gas pressure on the diffusion. The results predicted by the model are compared with the results of one-dimensional numerical modeling. Copyright (C) EPLA, 2013
