Global Scale-Invariant Dissipation in Collisionless Plasma Turbulence
Global Scale-Invariant Dissipation in Collisionless Plasma Turbulence
A higher-order multiscale analysis of the dissipation range of collisionless plasma turbulence is presented using in-situ high-frequency magnetic field measurements from the Cluster spacecraft in a stationary interval of fast ambient solar wind. The observations, spanning five decades in temporal scales, show a crossover from multifractal intermittent turbulence in the …
