Magneto-Hydro-Dynamic Stability of Fusion Plasmas

The control of large scale magnetic instabilities in fusion plasmas is essential for the successful operation of ITER and future fusion power plants. Large scale numerical simulations on the largest supercomputers are applied to study the physics of these instabilities, their consequences and the methods for control.

Simulations of instabilities in fusion plasmas, developing the predictive capability for their occurrence, consequences and control, are required for the preparation of operation of ITER and design of future machines

Fusion plasmas can suffer from global instabilities of the magnetic structure of the plasma. The so-called magnetohydrodynamic (MHD) instabilities, driven unstable by the plasma pressure and current, can cause fast losses of the thermal plasma energy. A typical time scale is of the order of 100ms to 1ms.
