Title: Simulations of Ar gas-puff Z-pinch radiation sources with double shells and central jets on the Z generator

Abstract

Radiation-magnetohydrodynamic simulations using the non-LTE Mach2-TCRE code in (r,z) geometry are performed for two pairs of recent Ar gas-puff Z-pinch experiments on the refurbished Z generator with an 8 cm diameter nozzle. One pair of shots had an outer-to-inner shell mass ratio of 1:1.6 and a second pair had a ratio of 1:1.

One- and two-dimensional modeling of argon K-shell emission from gas-puff Z-pinch plasmas

Journal Article Thornhill, J W ; Chong, Y K ; Apruzese, J P ; ... - Physics of Plasmas

In this paper, a theoretical model is described and demonstrated that serves as a useful tool for understanding K-shell radiating Z-pinch plasma behavior. Such understanding requires a self-consistent solution to the complete nonlocal thermodynamic equilibrium kinetics and radiation transport in order to realistically model opacity effects and the high-temperature state of the plasma. For this purpose, we have incorporated into the MACH2 two-dimensional magnetohydrodynamic (MHD) code [R. E. Peterkin et al., J. Comput. Phys. 140, 148 (1998)] an equation of state, called the tabular collisional radiative equilibrium (TCRE) model [J. W. Thornhill et al., Phys. Plasmas 8, 3480 (2001)], thatmore »« less

Study of Triple Ar Gas Puff Z-Pinches on 0.9-MA, 200-ns COBRA

Journal Article Qi, N. ; Rocco, S. V. ; Engelbrecht, J. ; ... - IEEE Transactions on Plasma Science

Ar gas puff z-pinch experiments were conducted on the 0.9 MA, 200 ns COBRA generator at Cornell University. In the experiments, a triple-nozzle gas valve was used to produce the zpinch load with concentric outer and inner gas puffs and a central gas jet. We used Planer Laser Induced Fluorescence (PLIF) to measure the initial gas profile of the load, two 4-frame 4-ns gated XUV cameras to image the imploding plasma, and filtered Photo- Conducting Diamond Detectors (PCDs) to measure the x-ray output. We have observed shock heating and/or photoionization of the dense center jet by the imploding plasma. Withmore »« less

X-ray results from a modified nozzle and double gas puff z pinch

Journal Article Chang, T ; Fisher, A ; Van Drie, A - Journal of Applied Physics; (USA)

The nozzle and the anode of the UCI (University of California, Irvine) {ital z}-pinch facility were modified to study the influence of the anode-cathode geometrical structure on the stability of the pinch and the x-ray yield of the pinch. The anode was modified from a honey-comb to a hollow cylinder with a 4-cm diameter and a {similar to}3.5-mm wall thickness, placed 2 cm below the cathode. The cavity in the center of the cathode was enlarged from 6-mm diameter to 36 mm. The design of the cathode and the anode showed a marked improvement of the pinch stability over themore »« less

Material effects on dynamics in triple-nozzle gas-puff Z pinches

Journal Article Narkis, J. ; Conti, F. ; Beg, F. N. - Physical Review. E

Here, the gas-puff Z pinch has a long history with myriad applications as an efficient neutron or x-ray source. Its simplicity as a load configuration makes it suitable for studying fundamental plasma physics phenomena such as instabilities and energy transport. For example, the implosion of cylindrical shells onto a fusion fuel are inherently susceptible to instability growth on their external surfaces; if such instabilities are unmitigated, then the consequences in terms of degraded performance can be substantial. Similarly, mitigating heat transport from a hot fuel to its colder surrounding container can make fusion conditions more easily achievable. Here we have conducted a systematic study of triple-nozzle (outer liner, inner liner, fuel) gas puffs using two-dimensional (2D) magnetohydrodynamic simulations to investigate the effect of load material on the relevant dynamics. Analogous to past studies on spherical blast waves and converging shock waves, a trend emerges linking increased radiative cooling, lower adiabatic index, and increased magneto-Rayleigh-Taylor instability growth. Notably, our results suggest that, for the present configuration, Ar radiates less than both Ne and Kr during the early stages of the implosion while mass is being swept up and perturbations begin to seed instability growth. Consequently, pinches with Ar on the outer surface exhibit more stable 2D behavior. Here we also present a parameter scan of thermonuclear neutron yield, Y, as a function of peak current, I_pk and dopant concentration with Ne or Ar, depending on the inner liner material. Above 6 MA, our results suggest Y ∝more »« less

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

Journal Article 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
