Analysis of linear MHD stability by using high n approximation
- 1. Japan Atomic Energy Agency, Fusion Research and Development Directorate, Naka, Ibaraki (Japan)
Description
Simplification of the physical model by using the high n approximation has been applied to the stability analysis of the edge-localized modes (ELM) in tokamak devices. The ideal MHD stability analysis code MARG2D incorporating the high n approximation is successfully applied to an eigen value problem and an initial value problem for the ELM analysis. It is found that the initial value problem including the high n approximation yields a fake solution due to higher order time-derivative terms. (T.I.)
