dc.description.abstract | The stability with respect to a peeling–ballooning mode (PBM) was investigated numerically with
extended MHD simulation codes in JET, JT-60U and future JT-60SA plasmas. The MINERVA-DI
code was used to analyze the linear stability, including the effects of rotation and ion diamagnetic drift
( *w i), in JET-ILW and JT-60SA plasmas, and the JOREK code was used to simulate nonlinear
dynamics with rotation, viscosity and resistivity in JT-60U plasmas. It was validated quantitatively
that the ELM trigger condition in JET-ILW plasmas can be reasonably explained by taking into
account both the rotation and *w i effects in the numerical analysis. When deuterium poloidal rotation
is evaluated based on neoclassical theory, an increase in the effective charge of plasma destabilizes
the PBM because of an acceleration of rotation and a decrease in *w i. The difference in the amount of
ELM energy loss in JT-60U plasmas rotating in opposite directions was reproduced qualitatively with
JOREK. By comparing the ELM affected areas with linear eigenfunctions, it was confirmed that the
difference in the linear stability property, due not to the rotation direction but to the plasma density
profile, is thought to be responsible for changing the ELM energy loss just after the ELM crash. A
predictive study to determine the pedestal profiles in JT-60SA was performed by updating the EPED1 model to include the rotation and *w i effects in the PBM stability analysis. It was shown that the plasma rotation predicted with the neoclassical toroidal viscosity degrades the pedestal performance by about 10% by destabilizing the PBM, but the pressure pedestal height will be high enough to achieve the target parameters required for the ITER-like shape inductive scenario in JT-60SA. | es |
