New Staged Z-Pinch Experiments on the Mega-Ampere Current Driver Zebra*

2017 IEEE International Conference on Plasma Science (ICOPS), 2017

Summary form only given. We report results from the latest staged Z-pinch experiments conducted on the 1MA Z-pinch Zebra facility at the University of Nevada, Reno. In these experiments a hollow shell of Krypton gas liner is injected through a supersonic nozzle (ID=2.0 cm), with a throat gap of 240 microns. The width of the anode-cathode gap is 1 cm. ...


X-Ray Spectroscopic Diagnostics of ICF Implosions on NIF Using KR Dopant*

2017 IEEE International Conference on Plasma Science (ICOPS), 2017

X ray spectroscopy is used on the NIF to diagnose the plasma conditions in the ignition target in indirect drive ICF implosions [1]. A platform is being developed at NIF where small traces of krypton are used as a dopant to the fuel gas for spectroscopic diagnostics using krypton line emissions. Amount of fraction of krypton dopant was varied in ...


A study of binary ion plasma expansion into laboratory generated plasma wakes

IEEE 1989 International Conference on Plasma Science, 1989

Summary Form only given, as follows. Plasma expansion into the wake of a large rectangular plate immersed in a collisionless, supersonic, binary ion plasma has been investigated. A new plasma source has been developed to generate equivelocity, binary ion plasma flows, which allows access to regions of parameter space that have previously been unavailable for laboratory studies.

DT Neutron Yield Modeling for Staged Z-Pinch Experiments on the 1MA Zebra Machine*

2017 IEEE International Conference on Plasma Science (ICOPS), 2017

Confinement of neutron secondaries (14.1MeV) in deuterium Z-pinch plasmas is of significant scientific and practical interest because it is similar to the confinement of 3.5MeV alpha particles produced in the fusion of deuterium and tritium nuclei. During the final Z-pinch stagnation stage, in very dense target plasmas, the alphas are expected to provide additional heating, and eventually lead to ignition. ...

  • New Staged Z-Pinch Experiments on the Mega-Ampere Current Driver Zebra*

    Summary form only given. We report results from the latest staged Z-pinch experiments conducted on the 1MA Z-pinch Zebra facility at the University of Nevada, Reno. In these experiments a hollow shell of Krypton gas liner is injected through a supersonic nozzle (ID=2.0 cm), with a throat gap of 240 microns. The width of the anode-cathode gap is 1 cm. The liner compresses a deuterium target plasma injected through a plasma gun with copper-tungsten walls. Axial magnetic field in the 1-2kG range, applied across the pinch region, stabilizes the Rayleigh-Taylor instabilities. Experimental measurements such as pinch current, X-ray signals, neutron yield, and streak images are compared with MACH2 radiation hydrodynamic code simulations. Krypton liner density profiles, obtained in separate nozzle charaterization measurements at UC San Diego, are input for MACH2. We also report preliminary results from neutron time of flight measurements. We analyze signatures of both primary(2.34MeV) and secondary neutrons (14.1MeV). Time of flight detectors include: (a) standard photomultipliers, and plastic scintillators and (b) gated, high sensitivity photomultipliers, and large area liquid scintillators.

  • X-Ray Spectroscopic Diagnostics of ICF Implosions on NIF Using KR Dopant*

    X ray spectroscopy is used on the NIF to diagnose the plasma conditions in the ignition target in indirect drive ICF implosions [1]. A platform is being developed at NIF where small traces of krypton are used as a dopant to the fuel gas for spectroscopic diagnostics using krypton line emissions. Amount of fraction of krypton dopant was varied in the experiments and was selected so as not to perturb the implosion. Simulations of the krypton spectra using a small atomic fraction of krypton in direct-drive exploding pusher with a range of electron temperatures and densities show discrepancies when different atomic models are used. We use our non-LTE atomic model with a detailed fine- structure level atomic structure and collisional-radiative rates to investigate the krypton spectra at the same conditions and generate synthetic spectra with a detailed multi-frequency radiation transport scheme from the emission regions of interest to analyze the experimental data and compare and contrast with the existing simulations at LLNL.

  • A study of binary ion plasma expansion into laboratory generated plasma wakes

    Summary Form only given, as follows. Plasma expansion into the wake of a large rectangular plate immersed in a collisionless, supersonic, binary ion plasma has been investigated. A new plasma source has been developed to generate equivelocity, binary ion plasma flows, which allows access to regions of parameter space that have previously been unavailable for laboratory studies. A krypton-neon plasma (mass ratio of 4.15) is used, and the ambient density ratio of neon to krypton is varied more than an order of magnitude. The expansion is limited to early times by the combination of plasma density, plasma drift speed, and vacuum chamber size. No previous experimental results exist for such early expansion times. New experimental results include: (1) the propagation of a rarefaction wave for each ionic component into the ambient plasma; (2) the formation of a plateau-like region in the neon (the lighter mass) ion current density when the neon ions are the minor ionic species in the ambient plasma; and (3) the acceleration of both ionic species, with neon accelerating at a higher rate than krypton. Results indicate that the plasma expansion process is the dominant filling mechanism of the near wake of a body under these experimental conditions.<>

  • DT Neutron Yield Modeling for Staged Z-Pinch Experiments on the 1MA Zebra Machine*

    Confinement of neutron secondaries (14.1MeV) in deuterium Z-pinch plasmas is of significant scientific and practical interest because it is similar to the confinement of 3.5MeV alpha particles produced in the fusion of deuterium and tritium nuclei. During the final Z-pinch stagnation stage, in very dense target plasmas, the alphas are expected to provide additional heating, and eventually lead to ignition. Here we present YDTcalculations for plasmas relevant to our planned April 2017 experiments on the UNR ZEBRA Facility, where Kyrpton gas liner implodes on a deuterium target injected with a plasma gun. Input to the mifti_MCDT code are Mach2 calculated (R,z) profiles of the Bz,Br,Bomagnetic field components, and Ni, and Tiplasma profiles, at one time instant during the ~2ns long stagnation stage. Kyrpton liner density profiles, obtained in separate nozzle characterization measurements at UC San Diego, are input for Mach2. Triton trajectories are followed in Monte Carlo code throughout the very dense plasma column: radially to its edge (r ~200μm), and vertically, to the anode and cathode metal boundaries.

  • Generation and diagnostics of mixed Ar/Kr clusters. Tunable source of dual-energy X-rays based on the clusters excitation by fs-laser

    Rayleigh scattering technique was proposed for diagnostics of mixed Ar/Kr clusters. Clusterization of krypton fraction was observed. Dual energy X-ray source with tunable line amplitudes, based on laser excitation of the mixed clusters has been developed. It was shown that the relative line yield in dual-energy X-rays can be controlled by selecting of proper fraction of initial gas mixture components.

  • 17 GHz excitation of argon ion and helium-krypton ion lasers

    A magnetron operating at 17 GHz delivers 40 kW pulses into a microwave coupling structure producing a transverse electric field of approximately 10/sup 6/ V/m. Laser action has been observed in a variety of Argon, Helium- Argon and Helium-Krypton gas mixtures. The microwave power absorption efficiency as a function of excitation frequency is considered. Time-resolved spectroscopy is used to monitor the variation of output against gas mixture ratio and pressure, and input power characteristics.<>

  • Planar Multijunction Thermal Converters with Increased Sensitivity Operated in Hermetically Sealed Housings Filled with Noble Gas

    The sensitivity of planar multijunction thermal converters (PMJTCs) was significantly increased by filling the housing with noble gases, preferably xenon or krypton. The performance was observed for more than one year and no degradation of sensitivity was found. Also the frequency response of the AC-DC transfer difference remains unchanged at high frequencies and even improves below 40 Hz. Using the lowest at present manufacturable heater resistance of 90 Ω with the noble gas filling, AC-DC transfer down to less than 70 mV compared to about 100 mV in air becomes possible.
