Recent 3D RMHD simulations [1] and experiments [2] have demonstrated that axially and azimuthally averaged dynamics of a strongly radiating stagnated Z-pinch column resembles a self-similar, cylindrically symmetric motion. The cold, rapidly imploding incident plasma transforms into the hot stagnated plasma when it gets heated and compressed in the diverging shock wave that propagates from the pinch...
Detailed spatially resolved spectroscopic analysis of a neon gas puff z pinch on the Weizmann 1 MA generator indicates that the radius of the K-shell emitting region grows to a maximum and then decreases during the radiation pulse1,2. ID Lagrangian simulations show the opposite trend because the emission arises from the inside surface of a dense shell that bounces off a hot, stripped central core...
Summary form only given. Full understanding of the dynamics, population kinetics, and energy budget of a K-shell radiating Z-pinch remains a challenging problem in high energy density plasma physics. Recently, detailed axially-imaged spectroscopic measurements were performed on a Ne gas puff driven by the Weizmann generator (500 kA in 500 ns). The Gaussian line widths and measured energy input into...
Summary form only given. The time-history of the ion-kinetic energy Ekion throughout the stagnation phase of a neon-puff, 500 ns, 600 kA, Z-pinch implosion was determined. The X-ray spectroscopic system provides a resolving power of 6700 and four consecutive time gated (~1 ns) spectra. A simultaneous axial imaging allows for studying the ion kinetic energy at 0.1-mm-resolution along the pinch column...
