Measurement of zero-frequency fluctuations generated by coupling between Alfven modes in the JET tokamak
Juan Ruiz Ruiz, Jeronimo Garcia, Michael Barnes +13
We report the first experimental detection of a zero-frequency fluctuation that is pumped by an Alfvèn mode in a magnetically confined plasma. Core-localized bidirectional Alfvèn m…

A self-sustaining mechanism for Internal Transport Barrier formation in HL-2A tokamak plasmas
W. H. Lin, J. Garcia, J. Q. Li +4
The formation of Internal Transport Barrier (ITB) is studied in HL-2A plasmas by means of nonlinear gyrokinetic simulations. A new paradigm for the ITB formation is proposed in whi…
