Pushing the limits of plasma length in inertial fusion laser-plasma interaction experiments

Description: We demonstrate laser beam propagation and low backscatter in laser produced hohlraum plasmas of ignition plasma length. At intensities I < 5 x 10{sup 14} W cm{sup -2} greater than 80% of the energy in a blue (3{omega}, 351 nm) laser is transmitted through a L=5-mm long, high-temperature (T{sub e} = 2.5 keV), high-density (n{sub e} = 5 x 10{sup 20} cm{sup -3}) plasma. These experiments show that the backscatter scales exponentially with plasma length which is consistent with linear theory. Th… more

Global polarization measurement in Au+Au collisions

Description: The system created in non-central relativisticnucleus-nucleus collisions possesses large orbital angular momentum. Dueto spin-orbit coupling, particles produced in such a system could becomeglobally polarized along the direction of the system angular momentum. Wepresent the results of Lambda and anti-Lambda hyperon global polarizationmeasurements in Au+Au collisions at sqrt sNN=62.4 GeV and 200 GeVperformed with the STAR detector at RHIC. The observed globalpolarization of Lambda and anti-Lambd… more

An X-ray Study of Shock-Recovered Tantalum Single Crystals

Description: In this paper, we report shock-induced new grains and residual lattice tension in tantalum single crystals. The single crystals with orientations in [001], [011], [111], and [123] directions are shocked at {approx}55 GPa in gas gun under almost identical conditions. New grains in the shocked crystals are revealed by x-ray scanning analysis. Rather than lattice compression that is frequently probed by in situ x-ray diffraction technique, we find significant residual lattice tension in the recove… more

Resonance transition 795-nm Rubidium laser using 3He buffer gas

Description: We report the first demonstration of a 795-nm Rubidium resonance transition laser using a buffer gas consisting of pure {sup 3}He. This follows our recent demonstration of a hydrocarbon-free 795-nm Rubidium resonance laser which used naturally-occurring He as the buffer gas. Using He gas that is isotopically enriched with {sup 3}He yields enhanced mixing of the Rb fine-structure levels. This enables efficient lasing at reduced He buffer gas pressure, improving thermal management in high average… more

Self-Consistent Criteria for Evaluation of Neutron Interaction

Description: New safe interaction criteria for containers of fissionable materials handled at the Oak Ridge Gaseous Diffusion Plant have been developed on the basis of an interaction theory using the basic concepts of a safe solid angle subtended by interacting containers, and the multiplication factor as determined by two-group theory for an individually safe containers The calculated results agree satisfactorily with experimental data obtained with identical interacting units involving both cylinders and … more

Multicomponent Transport through Realistic Zeolite Membranes: Characterization & Transport in Nanoporous Networks

Description: These research studies focused on the characterization and transport for porous solids which comprise both microporosity and mesoporosity. Such materials represent membranes made from zeolites as well as for many new nanoporous solids. Several analytical sorption techniques were developed and evaluated by which these multi-dimensional porous solids could be quantitatively characterized. Notably an approach by which intact membranes could be studied was developed and applied to plate-like and tu… more

Reconstruction of q- and p-profiles in ITER using External and Internal Measurements

Description: *This manuscript is in Russian* A method of calculation of uncertainties in equilibrium construction of q- and p-profiles in ITER using external magnetic measurements as well as signals from the plasma core on the Motion Stark line polarization (MSE-LP) and line shift (MSE-LS) is described. It is shown that recently proposed by Nova Photonics use of MSE-LS signal significantly improves the reconstruction of plasma profiles, which determine the magnetic configuration.

Adequate Yearly Progress (AYP): Growth Models Under the No Child Left Behind Act

Description: This report highlights the adequate yearly progress (AYP) concept of the No Child Left Behind Act of 2001. The AYP is the standard of eligibility for grants, of which states must implement AYP policies in all public schools and local education agencies (LEAs). The standard primarily utilizes state test scores to measure the school's eligibility for funding, schools that do not meet AYP standard for two or more consecutive years face consequences. Finally, the report tackles the idea of growth m… more
