Universal fluctuation spectrum of Vlasov-Poisson turbulence
Michael L. Nastac, Robert J. Ewart, James Juno +2
The thermal fluctuation spectrum of the electric field arising due to particle noise in a quiescent Vlasov-Poisson plasma was derived in the 1960s. Here, we derive the universal fl…

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…
