Tokamaks

In the conception of the ITER tokamak, several key challenging points have been identified. One of them is the necessity to understand and control the huge thermal loads that are directed to the divertor target plates from the scrape-off layer (SOL) region since they are at the edge of or above what can be handled by today’s materials. In the same spirit, the control of ELMs type instabilities that can also result in huge energy losses impacting the plasma facing components is considered as of crucial importance for the ITER program. The optimization of scenarii for designing the discharges of ITER and WEST will be addressed as well as some problems of ionospheric plasma.
