Studying the Intermittency of Broadband Magnetic Fluctuations

The Bryn Mawr Experiment generates broadband magnetic fluctuations which exhibit intermittent behavior. We report on the progress of the intermittency study using high-order statistical analysis of broadband magnetic fluctuations. The Bryn Mawr Experiment injects magnetic helicity with a magnetized coaxial plasma gun into a flux-conserving cylindrical vacuum chamber. The vacuum chamber has no background magnetic which allow flows and magnetic fields to evolve dynamically. Magnetic field measurements (bdot-probes) show intermittent broadband fluctuations. Understanding this intermittent behavior would provide insight on the dissipation of magnetic energy and the nature of the broadband magnetic fluctuations.
