 From the theoretical perpective we should consider different mechanisms:

 From the experimental perspective the goal is the investigation and characterization of the influence of ECRH on / off power heating in the dynamics of edge & core fluctuations and transport in the TJ-II stellarator, including: 1) Level of fluctuations, 2) Phase relation between density and potential fluctuations, 3) Turbulent ExB transport.
