On coupled plasma-wall instabilities.

Although approximate, but rather simple approach to numerical study of coupled plasma-wall instabilities is suggested. One of important advantages of this approach is related to splitting of plasma and wall models, which allows using the results of different plasma and wall models without performing any additional simulations. For simplicity only synergistic effects caused by hydrogen fluxes are considered . However, this approach could be easily extended to account for impurity effects. Finally, we note that the response functions needed for dispersion equation could be deduced from experimental data in a specially design experimental set up.
