Recorded talk: Generating and diagnosing turbulence in pulsed-power driven magnetised plasmas

This is a recorded version of the talk I gave last week at the APS DPP annual meeting. We found some unexpected behaviour in what we thought would be a simple collision between a magnetised plasma and a planar obstacle. We diagnose the plasma flows to determine the relevant parameters and length scales, which help us to understand what instabilities might be driving turbulence in this plasma.
