Dispersion Relation of Stratified Electrothermal Instability in Warm, Dense, Tamped Aluminum-6061 with Current in a Skin Layer

Autor: T. M. Hutchinson, Edmund Yu, Bruno S. Bauer, Thomas James Awe, Stephan Fuelling, K.C. Yates, William Graham Yelton

Publikováno v: 2018 IEEE International Conference on Plasma Science (ICOPS).

The dispersion relation of the stratified electrothermal instability (ETI) has been measured on the surface of aluminum-6061 rods pulsed with rapidly rising lineal current density ( $3\times 10^{15}$ A m-1s-1 for 70 ns). The $500-\mu \mathrm{m}$ rod

Publikováno v: Physical Review E. 97

A direct observation of the stratified electrothermal instability on the surface of thick metal is reported. Aluminum rods coated with 70μm Parylene-N were driven to 1 MA in 100ns, with the metal thicker than the skin depth. The dielectric coating s

Meissner Effect in Ultra-Dense Protium p(l = 0, s = 2) at Room Temperature: Superconductivity in Large Clusters of Spin-Based Matter

Autor: Leif Holmlid, Stephan Fuelling

Publikováno v: Journal of Cluster Science. 26:1153-1170

Ultra-dense protium p(l = 0) is superfluid at room temperature, as is its more often studied deuterium counterpart D(l = 0). p(l = 0) can be deposited on surfaces by a source which produces a stream of clusters. A magnetic field strongly influences t

Addressing Short Trapped-Flux Lifetime in High-Density Field-Reversed Configuration Plasmas in FRCHX

Publikováno v: IEEE Transactions on Plasma Science. 42:1179-1188

The objective of the field-reversed configuration heating experiment (FRCHX) is to obtain a better understanding of the fundamental scientific issues associated with high-energy density laboratory plasmas (HEDLPs) in strong, closed-field-line magneti

Significant change in threshold for plasma formation and evolution with small variation in copper alloys driven by a mega-ampere current pulse

Publikováno v: Physics of Plasmas. 26:042708

We report the first observation of a significant change in plasma formation and evolution caused by a small change in the material composition (metal alloy). Thick copper rod alloys were varied in the initial diameter from 0.5 mm to 1.59 mm and pulse

Magnetically imploded liners assemble high-energy-density plasmas for radiation effects and inertial confinement fusion experiments. The stagnation pressures and temperatures achieved are limited by the Magneto-Rayleigh-Taylor (MRT) instability, whic

Ultra-dense deuterium D(−1) is expected to be both a superfluid and a superconductor as shown by recent theoretical research. Condensed D(−1) can be deposited on surfaces by a source which produces a stream of clusters. A magnetic field strongly
