Anisotropic Properties of Broadband Magnetic Fluctuations Generated with a Magnetized Plasma Gun Source

POSTER

Abstract

Turbulence is a chaotic process caused by nonlinear interactions that transfer energy across scales. Magnetohydrodynamic (MHD) turbulence; a similar process within conducting media, like plasmas, is inherently anisotropic when a strong guild field is present. Understanding the anisotropic properties of MHD turbulence would provide insight on the nature of MHD turbulence and help identify universal features of MHD turbulence. Here we present a study on the anisotropic properties of broadband magnetic fluctuations, using both local and global mean fields, on the Bryn Mawr Experiment. The Bryn Mawr Experiment is an MHD turbulence experiment that injects plasma with dynamic magnetic fluctuations, using a coaxial plasma gun, into a 270cm long, 24cm diameter flux-conserving zero guide field vacuum chamber. Mean magnetic field measurements reach strengths of 3.2kGauss on average and maintain stationary broadband magnetic activity for over 80us.
