Abstract
The interaction of electrons with plasma walls has been a topic of great interest in modeling the plasma for fusion reactors. The selection of a suitable plasma wall coating element is critical in the design of reactors like the Tokomak. In any plasma model, phenomena like wall erosion, transport of impurities, and redeposition on the walls are vital. Various elements are used as coatings on the plasma walls like Li, Be, B, Ti, and Fe. Hence, in this article we have presented a method for calculating the total ionization cross section for these elements. The cross sections are calculated in the energy range from the ionization threshold to 2 keV. The results obtained are found to be consistent and agree well with other measurements and theories wherever available.
