description: The subject of the graduate qualification work is âInvestigation of coronal and collision-radiation models applicability in high-frequency dischargeâ. The given work is devoted to define boundaries of applicability of coronal and collision-radiation models in high-frequency discharge. Purpose of the work is to program and to get numeric results of atomic hydrogen population. The result of the program is numerical data which describe population on each level with different discharge densities and equal temperature, with different discharge temperature and equal density. These data are compared to each other in order to define boundaries of coronal model applicability. During this process collision-radiation model considered to be much more accurate.Result of numerical modeling shows, that accuracy of coronal model decreases with growth of density. For high densities of plasma it can be used only for low levels (main quantum number of the order of 10). With increasing temperature, the coronal model, on the contrary, more accurately describes the population of the atom. These results can be used in cleaning discharge spectroscopy, which removes impurity particles from optical mirror surface. Analyses of spectroscopy data for defining impurity particles density become possible with the help of numerical modeling of population of such particles. Results of this work shows that coronal model in most cases can be applied for high-frequency discharge spectroscopy problems, because it describes the low levels of atomic hydrogen with high accuracy.
