The Actinide Analytical Chemistry (CAAC) group at Los Alamos National Laboratory (LANL) uses the LabWare LIMS (LabWare 7) system to manage our samples and material at risk. The LIMS system also provides other functionality which the Plasma Spectroscopy (PS) team has developed along with our LIMS team to provide streamlining and automation of all sample related actions required by PS.

Our mission as a DOE national security science laboratory is to develop and apply science, technology, and engineering solutions that: (1) Ensure the safety, security, and reliability of the US nuclear deterrent; (2) Protect against the nuclear threat; and (3) Solve Energy Security and other emerging national security challenges.
Since 1984 INFN scientists performing experiments at Fermilab have been running a two month summer training program for Italian students at the lab. In 1984 the program involved only a few physics students from the Pisa group, but it was later extended to other groups and to engineering students. Since 2004 the program has been supported in part by DOE in the frame of an exchange agreement with INFN. The Fermilab training programs spanned from data analysis to design and construction of particle detectors and accelerator components, research on superconductive elements, theory of accelerators, and analysis of astrophysical data. At the other US laboratories the offered training was on Space Science.
The concept of net-zero carbon microgrids (NZMs) has received significant interest in recent years considering its promises to provide both energy resilience and carbon reduction. This paper investigates the practical constraints of NZM deployment in a government facility, exploring various cases revolving around the objectives of cost, emission, and energy resilience. The technoeconomic results for one of the Idaho National Laboratory (INL) facilities are discussed to identify a practical and economic approach to achieve the net-zero target considering both present and future scenarios. The study shows the carbon reduction, resilience, and economic success of net-zero initiatives are tied directly to the energy portfolio of its electricity provider. The NZMs typically required a hybrid mix of renewable generation and storage assets to maximize onsite clean generation and to provide reliable power during grid outages. Besides supporting the ongoing net-zero effort at INL, this work also provides a framework that can be directly used in other facilities aspiring to become a net zero in the future.
Extreme ultraviolet spectra of C, O, F, Ne, S, Ar, Fe, and Ni have been excited in an electron beam ion trap and studied with much higher resolution than available on the Solar Dynamics Observatory (SDO) in order to ascertain the spectral composition of the SDO/Atmospheric Imaging Assembly (AIA) observations. We present our findings in the wavelength range 182-200 Å, which, overall, corroborate the working models of how to interpret the SDO/AIA data. We find, however, that the inclusion of a number of additional lines might improve the data interpretation.
In September of 2012 the Plutonium Sustainment program at LANL completed or addressed the following high-level activities: 1) Completed assembly, inspection, packing, and approvals for Pollux. Completed shipment to DAF in early October in accordance with the Gemini Core Team’s schedule. 2) Delivered the draft Program Implementation Plan and revised repeatedly. 3) Met with Kansas City Plant staff to “kick-off” the non-nuclear pit-component production mission. All MRT L2 Milestones 4195-4198 or the relevant PBIs associated with Plutonium Sustainment have been met and evidence packages submitted. The year-end budget/performance indices were 0.96 (S.P.I.) and 1.00 (C.P.I.). Table 1 identifies all Baseline Change Requests (BCRs) that were initiated, in process, or completed during the month. The earned value metrics overall for LANL are within acceptable thresholds, so no high-level recovery plan is required. Note that the planned (budget) and earned value for September includes planned carryover holdbacks (no allocation) with no associated FY12 costs. This has a minor (positive) impact on S.P.I. and a significant (positive) impact on the C.P.I. For Pu Sustainment overall, the C.P.I. in September neglecting the $10.75M holdback is 0.90. Likewise, the C.P.I. for FY12 is 1.004. With the facility infrastructure element removed, the C.P.I. in September becomes 0.92. Likewise, the C.P.I. for FY12 is 0.992. Again neglecting the holdback, the S.P.I. numbers for Pu Sustainment overall are 0.94 (Sept) and 0.96 (FY12) and with the facility infrastructure element removed 0.95 (Sept) and 0.95 (FY12).
This procedure covers the determination of the percent 14 C in biogenic gasoline, jet fuel, and diesel range hydrocarbons prepared from distillation of hydrotreated pyrolysis oils and blended with fossil derived hydrocarbons (e.g. fossil diesel, gasoline, jet, or toluene). Either an internal 14C standard or a color quench curve is used to correct for potential signal quenching effects. Recent publications provide some background of direct LSC methods used for determination of biogenic fuel content.
Here, this article describes the establishment, over a period of 10 years or so, of a multi-user, institution-wide facility for the characterization of materials and devices at the nanoscale. Emphasis is placed on the type of equipment that we have found to be most useful for our users, and the business strategy that maintains its operations. A central component of our facility is an aberration-corrected environmental transmission electron microscope and its application is summarized in the studies of plasmon energies of silver nanoparticles, the band gap of PbS quantum dots, atomic site occupancy near grain boundaries in yttria stabilized zirconia, the lithiation of silicon nanoparticles, in situ observations on carbon nanotube oxidation and the electron tomography of varicella zoster virus nucleocapsids.

The historic observations of the neutron star merger GW170817 advanced our understanding of r-process nucleosynthesis and the equation of state (EOS) of neutron rich matter. Simple neutrino physics suggests that supernovae are not the site of the main r-process. Instead, the very red color of the kilonova associated with GW170817 shows that neutron star (NS) mergers are an important r-process site. We now need to measure the masses and beta decay half-lives of very neutron rich heavy nuclei so that we can more accurately predict the abundances of heavy elements that are produced. This can be done with new radioactive beam accelerators such as the Facility for Rare Isotope Beams (FRIB). GW170817 provided information on the deformability of NS and the equation of state of dense matter. The PREX II experiment will measure the neutron skin of {sup 208}Pb and help constrain the low density EOS. As the sensitivity of gravitational wave detectors improve, we expect to observe many more events. We look forward to exciting advances and surprises!.
