Topic: Understand L-H Transition from Eigenstates Jumps of Mirco-instabilities
Abstract:
We discuss the new understanding to a long-standing unclear and challenged problem in magnetic confinement fusion, i.e., the mechanisms of H-mode and the L-H transition. It is found by first principle gyrokinetic simulation of the H-mode experiment and eigenmode model theory that the L-H transition can originate from eigenstates jumps of mirco-instabilities.
