Abstract:We present a technique to measure the time-resolved velocity and ion sound speed in magnetized, supersonic highenergy-density plasmas. We place an inductive ('b-dot') probe in a supersonic pulsed-power-driven plasma flow and measure the magnetic field advected by the plasma. As the magnetic Reynolds number is large (R M > 10), the plasma flow advects a magnetic field proportional to the current at the load. This enables us to estimate the plasma flow velocity as a function of time from the delay between the cu… Show more
