Progress on the ITER ECRH upper launcher steering mirror identification and control
2009
Fusion Engineering and Design
The main objective of the ITER ECRH upper launcher (UL) is to control magnetohydrodynamic activity, in particular neoclassical tearing modes (NTMs), by driving several MW of EC Current near the q = 1, 3/2, 2 flux surfaces, where NTMs are expected to occur.
