Abstract

High-velocity high-energy-density plasma jets are an invaluable tool for studying plasma-material interactions under extreme thermal, physical, chemical, and electrostatic stresses. Such a jet has been generated in an experimental facility utilizing a pulsed plasma deflagration accelerator. Time-averaged and fast-frame-rate intensified charge-coupled device images of the plasma jet are presented, showing a concentrated high-density plasma near the exit that is characterized with laser interferometry.
