We present results from magnetised bow shock experiments performed on the Magpie (∼1 MA, 250 ns) pulsed-power facility. Bow shocks are formed around cylindrical conducting obstacles (diameter ∼0.5 mm) positioned in a supersonic, super-Alfenic, plasma flow (MS > 3, MA > 2.5, Vflow ∼70 km/s). This radially diverging flow is produced by an exploding wire array z-pinch, and carries an embedded azimuthal...
The use of plasma flows generated by pulsed power facilities provides a natural platform for designing magnetized HEDLA experiments. The plasma in this case is created and accelerated by the JxB force of the driving, ∼Mega-Ampere level currents, forming plasma flows with embedded, frozen-in magnetic fields. Here we present several recent experiments performed on the MAGPIE pulsed power facility, focusing...
An experiment is presented in which the x-ray emission from a stagnated wire array z-pinch is used to photo-ionise gas inside a gas cell. Photo-ionisation studies with x-rays from wire array implosions on the Z facility at Sandia National Labs used a gas cell positioned side-on and at large distances from the pinch1. Due to the much smaller radiation power from a 1 MA z-pinch, in our experiments the...
