Why is there decoupling between particle and energy transport channels at the transition to improved confinement regimes?. Physics behind uncoupled transport channels is a relevant open question for understanding both ELM control techniques (e.g. using RMP) as part of the ITER base-line scenario and the development of plasma scenarios without ELMs (e.g. I-mode). Interestingly, uncoupled transport channels has been also reported in stellarators / heliotrons (e.g. TJ-II <ref> C. Hidalgo et al., PPCF 46 (2004) 287A </ref>). | Why is there decoupling between particle and energy transport channels at the transition to improved confinement regimes?.
