[en] This report is based on a ten-week program on Gluons and the quark sea at high-energies, which took place at the Institute for Nuclear Theory (INT) in Seattle in Fall 2010. The principal aim of the program was to develop and sharpen the science case for an Electron-Ion Collider (EIC), a facility that will be able to collide electrons and positrons with polarized protons and with light to heavy nuclei at high energies, offering unprecedented possibilities for in-depth studies of quantum chromodynamics (QCD). This report is organized around the following four major themes: (i) the spin and flavor structure of the proton, (ii) three dimensional structure of nucleons and nuclei in momentum and configuration space, (iii) QCD matter in nuclei, and (iv) Electroweak physics and the search for physics beyond the Standard Model. Beginning with an executive summary, the report contains tables of key measurements, chapter overviews for each of the major scientific themes, and detailed individual contributions on various aspects of the scientific opportunities presented by an EIC.

[en] The workshop on opportunities for polarized He-3 in RHIC and EIC was targeted at finding practical ways of implementing and using polarized He-3 beams. Polarized He-3 beams will provide the unique opportunity for first measurements, i.e, to a full quark flavor separation measuring single spin asymmetries for p⁺, p^- and p⁰ in hadron-hadron collisions. In electron ion collisions the combination of data recorded with polarized electron proton/He-3 beams allows to determine the quark flavor separated helicity and transverse momentum distributions. The workshop had sessions on polarized He-3 sources, the physics of colliding polarized He-3 beams, polarimetry, and beam acceleration in the AGS Booster, AGS, RHIC, and ELIC. The material presented at the workshop will allow making plans for the implementation of polarized He-3 beams in RHIC.

[en] A Polarized ³He Ion Source in under development for use at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. The gas will be polarized using metastability exchange optical pumping, then transferred into the Electron Beam Ion Source for ionization. Nuclear polarization of order 70% is expected under optimal conditions, and roughly 10¹¹ doubly-ionized ³He⁺⁺ ions will be created in each 20 μs pulse.

[en] The layout and main parameters of the e-ring for EIC project are presented. Optics properties to fulfill so-called spin-transparency conditions to obtain sufficient polarization degree at IP are given. The possibility of using super-bend magnets for polarization time in a wide energy range to decrease is also discussed

[en] We have used fluorescence scanning near-field microscopy to characterize polymer blends for electroluminescent applications, and thereby identify compositional nonhomogeneities. In particular, we have focused on the binary system constituted by poly(9,9'-dioctylfluorenealt-benzothiadiazole) and poly(9,9'-dioctylfluorene) (PFO), known to give efficiencies of up to 22 cd/A in light-emitting devices with suitable electrodes. Our primary aim was the assignment of the morphological features revealed in shear-force and atomic-force images of spin-coated films, and suggestive of phase separation on a 300-nm-length scale. From analysis of the fluorescence images (325 and 488 nm excitation), and quantitative correlation of optical and topographic data, we identify the raised features with PFO-rich regions. However, the limited variation in fluorescence intensity reveals a high extent of mixing within each phase on the length scale accessible in our experiment, approximately 100 nm for our focused-ion-beam-processed probe apertures. copyright 2001 American Institute of Physics

[en] The present understanding of the spin structure of the nucleon is described. The world's data on spin-dependent deep inelastic scattering is summarized with particular emphasis on the new data from the last year. Next-to-leading order (NLO) QCD analysis of existing data provides another successful test of QCD. However, the uncertainty arising from the low x extrapolation provides a serious impediment to extracting information on the spin structure of the nucleon using sum rules formed from inclusive data. The NLO analyses suggest that the gluon contribution to the nucleon spin is sizable. Possible initiatives to directly probe the gluon spin are described. Semi-inclusive measurements at present underway will study new aspects of the nucleon spin structure

[en] The total system life-cycle cost (TSLCC) analysis for the Department of Energy's (DOE) Civilian Radioactive Waste Management Program is an ongoing activity that helps determine whether the revenue-producing mechanism established by the Nuclear Waste Policy Act of 1982--a fee levied on the producers of nuclear power--is sufficient to cover the cost of the program. This paper summarizes the program cost estimates in the third fee adequacy evaluation conducted in January 1985. Costs for reference waste-management program were estimated to be 24 to 30 billion (1984) dollars. Costs for the sensitivity cases studied ranged from 21 to 35 billion dollars. Factors such as repository location, quantity of waste generated, transportation cask technology, and repository startup dates were shown to exert substantial impacts on total-system costs
