A Stability of LCLS Linac Modulators
Information concerning to a stability of LCLS RF linac modulators is allocated in this paper. In general a 'pulse-to-pulse' modulator stability (and RF phase as well) is acceptable for the LCLS commission and FEL programs. Further modulator stability improvements are possible and approaches are discussed based on our experimental results.

Axion-Like Particle Imprint in Cosmological Very-High-Energy Sources
Discoveries of very high energy (VHE) photons from distant blazars suggest that, after correction by extragalactic background light (EBL) absorption, there is a flatness or even a turn-up in their spectra at the highest energies that cannot be easily explained by the standard framework. Here, it is shown that a possible solution to this problem is achieved by assuming the existence of axion-like particles (ALPs) with masses {approx} 1 neV. The ALP scenario is tested making use of observations of the highest redshift blazars known in the VHE energy regime, namely 3C 279, 3C 66A, PKS 1222+216 and PG 1553+113. In all cases, better fits to the observed spectra are found when including ALPs rather than considering EBL only. Interestingly, quite similar critical energies for photon/ALP conversions are also derived, independently of the source considered.

Laboratory Studies of Processing of Carbonaceous Aerosols by Atmospheric Oxidants/Hygroscopicity and CCN Activity of Secondary & Processed Primary Organic Aerosols
The atmosphere is composed of a complex mixture of gases and suspended microscopic aerosol particles. The ability of these particles to take up water (hygroscopicity) and to act as nuclei for cloud droplet formation significantly impacts aerosol light scattering and absorption, and cloud formation, thereby influencing air quality, visibility, and climate in important ways. A substantial, yet poorly characterized component of the atmospheric aerosol is organic matter. Its major sources are direct emissions from combustion processes, which are referred to as primary organic aerosol (POA), or in situ processes in which volatile organic compounds (VOCs) are oxidized in the atmosphere to low volatility reaction products that subsequent condense to form particles that are referred to as secondary organic aerosol (SOA). POA and VOCs are emitted to the atmosphere from both anthropogenic and natural (biogenic) sources. The overall goal of this experimental research project was to conduct laboratory studies under simulated atmospheric conditions to investigate the effects of the chemical composition of organic aerosol particles on their hygroscopicity and cloud condensation nucleation (CCN) activity, in order to develop quantitative relationships that could be used to more accurately incorporate aerosol-cloud interactions into regional and global atmospheric models. More specifically, the project aimed …

New Meteorlogical Data for Ventsar XL
Every five years Savannah River National Laboratory (SRNL) generates an updated meteorological database to facilitate dosimetric calculations of accident and routine release scenarios for onsite and offsite populations. This information becomes the input of various environmental dosimetry codes run by the Environmental Dosimetry Group (EDG) at SRNL. The three most recent databases prior to the current one were completed for the time periods 1987-1991, 1992-1996, and 1997-2001. The current database covers the period 2002-2006. This study represents a portion of a larger study to compare the meteorological data among these four five-year periods and focuses on updating VENTSAR XL{copyright} for the current meteorological database. The updated meteorological data are also applied in other dosimetry models approved for risk and dose assessment at Savannah River Site (SRS). VENTSAR XL{copyright} is a Gaussian Plume model that includes building effects and plume rise. The typical input involves the location of the release, building dimensions, distance to the building, release height, vent diameter, vent gas temperature, gas molecular weight, ambient air temperature, breathing rate, meteorological conditions, radionuclides and their amount released. The output is easily converted into tables and graphs for further analysis and shows the concentrations and pathway doses for each of the …

Search for the Xi(2220) and Study of the X(3872) at BaBar
The BABAR Collaboration performed a search for x (2220) production in the initial-state radiation process e{sup +}e{sup -} {yields} {gamma} J/{Psi}, J/{Psi} {yields} {gamma}K{sup +}K{sup -} or J/{Psi} {yields} {gamma}K{sub S}{sup 0}K{sub S}{sup 0}. No evidence for the {xi} (2220) resonance has been found. The 90% confidence level upper limits on the product of branching fractions are sensitive to the spin and helicity hypotheses. These upper limits are of the order 10{sup -5}, below the values reported in previous experiments. Also at BABAR, the decays B {yields} J/{Psi} {pi}{sup +}{pi}{sup -}{pi}{sup 0}K are studied to search for the decay X(3872) {yields} J/{Psi}{gamma}. This search yields a four standard deviation evidence for X(3872) {yields} J/{Psi}{omega}, with product branching fractions of {Beta}(B{sup +} {yields} X(3872)K{sup +}) x {Beta}(X(3872) {yields} J/{Psi}{omega}) = [0.6 {+-} 0.2(stat) {+-} 0.1(syst)] x 10{sup -5}, and {Beta}(B{sup 0} {yields} X(3872)K{sup 0}) x {Beta}(X(3872) {yields} J/y{Psi}) = [0.6 {+-} 0.3(stat) {+-} 0.1(syst)] x 10{sup -5}. A detailed study of the {pi}{sup +}{pi}{sup -}{pi}{sup 0} mass distribution from X(3872) decay favors a negative-parity assignment but does not rule out the positive-parity hypothesis.

Final report - Reduction of mercury in saturated subsurface sediments and its potential to mobilize mercury in its elemental form
The goal of our project was to investigate Hg(II) reduction in the deep subsurface. We focused on microbial and abiotic pathways of reduction and explored how it affected the toxicity and mobility of Hg in this unique environment. The project’s tasks included: 1. Examining the role of mer activities in the reduction of Hg(II) in denitrifying enrichment cultures; 2. Investigating the biotic/abiotic reduction of Hg(II) under iron reducing conditions; 3. Examining Hg(II) redox transformations under anaerobic conditions in subsurface sediments from DOE sites.

Baseline LAW Glass Formulation Testing
The major objective of the baseline glass formulation work was to develop and select glass formulations that are compliant with contractual and processing requirements for each of the LAW waste streams. Other objectives of the work included preparation and characterization of glasses with respect to the properties of interest, optimization of sulfate loading in the glasses, evaluation of ability to achieve waste loading limits, testing to demonstrate compatibility of glass melts with melter materials of construction, development of glass formulations to support ILAW qualification activities, and identification of glass formulation issues with respect to contract specifications and processing requirements.

[Photograph of Salado High School Graduates, 1945]
Photograph of a group of 18 teenage young men and women arranged in three rows in front of a brick wall, with a tree just behind the group, on the right. The members of the group are all wearing medium-colored, long academic robes with white collars, and medium-colored, square academic hats tilted down to the left. There are six male members total, two sitting on the right side of the bottom row, and four occupying the four middle spaces of the top row. The students on the front row are sitting down, while the row behind them is standing, and the back row is standing on some kind of raised structure. A white, rectangular sticker on the back of the photo indicates the group is the Salado High School graduating class of 1945.
