Turbulence studies using self-organized magnetic structures in a plasma wind tunnel

An overview and recent progress of activities at the Bryn Mawr Plasma Laboratory (BMPL) is presented. The main experiment at the facility, the Bryn Mawr eXperiment (BMX), consists of a 4mF, 2kV pulse-forming network that generates \textasciitilde 180us of stationary broadband fluctuations of magnetic field and plasma using a magnetized coaxial plasma gun source. These self-organized magnetized structures are launched into a 2.7m flux-conserving cylindrical wind tunnel. Single-loop magnetic pickup coils measure fluctuating magnetic field and time-delay estimated velocity. Multipoint measurements of spectra are made from linear arrays of probes along the axial direction of the chamber.
