Relativistic effects in EBW damping are crucial. If speed is of maximum importance, the Decker and Ram weakly-relativistic damping can be used, bearing in mind its limitations. Saveliev and the fully-relativistic calculation are in good agreement. The Saveliev term seems to suffer more from numerical difficulties and also does not provide separate harmonics damping necessary for current drive calculations. Hence, the fully-relativistic calculation, with a proper choice of numerical parameters, seems to be a better choice.
