Taylor Scale and Magnetic Reynolds Number Estimation via Two-Point Spatial Correlations

The Bryn Mawr Plasma Laboratory (BMPL) is a new facility investigating plasma turbulence. Here, spatial correlation analysis of magnetic fluctuations within the Bryn Mawr Magnetohydrodynamic Experiment (BMX) is used to estimate outer and inner scales of the inertial range of the energy cascade. These measurements are made using an array of magnetic pickup probes aligned parallel to the bulk flow of the plasma. With these estimates a magnetic Reynolds number is calculated. The spatial correlation scale and the Taylor microscale are used as the outer scale and inner scale respectively. This presentation represents the first BMX results of plasma turbulence properties.
