Imaging the visible emissions from plasmas in pulsed power experiments
News Article, March 16, 2023 • The center section of Sandia's Z Machine Low density plasmas are predicted to impact Sandia’s Z machine experiments in a variety of ways. Magnetic Resonance Tomography instability development during the target implosion can lead to broad trailing density profiles and potentially redistribute current away from the on-axis stagnation region. Low...
