Abstract

The ion-kinetic energy throughout K emission in a stagnating plasma was determined from the Doppler contribution to the shapes of optically thin lines. X-ray spectroscopy with a remarkably high spectral resolution, together with simultaneous imaging along the pinch, was employed. Over the emission period, a drop of the ion-kinetic energy down to the electron thermal energy was seen. Axially resolved time-dependent electron-density measurements and absolute intensities of line and continuum allowed for investigating, for the first time, each segment of the pinch, the balance between the ion-kinetic energy at the stagnating plasma, and the total radiation emitted. Within the experimental uncertainties, the ion-kinetic energy is shown to account for the total radiation.

Ion Temperature and Hydrodynamic-Energy Measurements in a Z-Pinch Plasma at Stagnation

Kroupp, E. ; Osin, D. ; Starobinets, A. ; ... - Physical Review Letters

The time history of the local ion kinetic energy in a stagnating plasma was determined from Doppler-dominated line shapes. Using independent determination of the plasma properties for the same plasma region, the data allowed for inferring the time-dependent ion temperature, and for discriminating the temperature from the total ion kinetic energy. It is found that throughout most of the stagnation period the ion thermal energy constitutes a small fraction of the total ion kinetic energy; the latter is dominated by hydrodynamic motion. Both the ion hydrodynamic and thermal energies are observed to decrease to the electron thermal energy by themore »« less

One- and two-dimensional density and temperature measurements of an argon-neon Z-pinch plasma at stagnation

Wong, K.L. ; Springer, P.T. ; Hammer, J.H. ; ... - AIP Conference Proceedings

In order to benchmark and improve current 2D radiation magnetohydrodynamic (MHD) models of Z-pinch plasmas, we have performed experiments which characterize the plasma conditions at stagnation. In the experiments the SATURN pulsed power facility at Sandia National Laboratory was used to create an imploding Ar-Ne plasma. An absolutely calibrated, high resolution space- and time-resolving Johann crystal spectrometer was used to infer the electron temperature T{sub e} from the slope of the hydrogenlike Ne free-bound continuum, and the ion density n{sub i} from the Stark broadening of the Ar heliumlike Rydberg series. 2D electron temperature profiles of the plasma are obtainedmore »« less

Ion probe beam experiments and kinetic modeling in a dense plasma focus Z-pinch

Schmidt, A., E-mail: schmidt36@llnl.gov ; Ellsworth, J., E-mail: schmidt36@llnl.gov ; Falabella, S., E-mail: schmidt36@llnl.gov ; ... - AIP Conference Proceedings

The Z-pinch phase of a dense plasma focus (DPF) emits multiple-MeV ions in a ∼cm length. The mechanisms through which these physically simple devices generate such high energy beams in a relatively short distance are not fully understood. We are exploring the origins of these large gradients using measurements of an ion probe beam injected into a DPF during the pinch phase and the first kinetic simulations of a DPF Z-pinch. To probe the accelerating fields in our table top experiment, we inject a 4 MeV deuteron beam along the z-axis and then sample the beam energy distribution after itmore »« less

Effective versus ion thermal temperatures in the Weizmann Ne Z-pinch: Modeling and stagnation physics

Giuliani, J. L. ; Thornhill, J. W. ; Dasgupta, A. ; ... - Physics of Plasmas

The difference between the ion thermal and effective temperatures is investigated through simulations of the Ne gas puff z-pinch reported by Kroupp et al. [Phys. Rev. Lett. 107, 105001 (2011)]. Calculations are performed using a 2D, radiation-magnetohydrodynamic code with Tabular Collisional-Radiative Equilibrium, namely Mach2-TCRE [Thornhill et al., Phys. Plasmas 8, 3480 (2001)]. The extensive data set of imaging and K-shell spectroscopy from the experiments provides a challenging validation test for z-pinch simulations. Synthetic visible images of the implosion phase match the observed large scale structure if the breakdown occurs at the density corresponding to the Paschen minimum. At the beginningmore »« less
