Los Alamos National Laboratory: SULI Appointment

The progenitors of gamma-ray bursts - the brightest explosions in our universe - are still poorly understood. It has been suggested that massive stars collapsing in interacting binary systems (i.e. with a closely orbiting compact object companion) can provide the necessary angular momentum and dense surrounding medium to explain observations of radio-loud gamma-ray bursts. We explore this progenitor system using the population synthesis code COSMIC. We explore the dependence of the properties of an interacting binary systems - including the remnant types and their masses - on metallicity and mass raction of the binary system. We also explore how the rates of populations of these systems depend on metallicity. Our findings help constrain what properties lead to viable GRB progenitors, especially radio loud GRBs.

Los Alamos National Laboratory Triad ST&E Committee Meeting Update: Entrepreneurial programs [Slides]

Why do our staff need an entrepreneurial mindset? “…dramatic change will be required to meet the needs of the deterrent today and into the future. This will require a shift away from highly conservative technical decision making to a risk informed approach, the adoption of modern manufacturing technologies and approaches and embrace of digital tools..."

Los Alamos National Laboratory Laboratory Directed Research and Development Program: FY23 Annual Progress Report- Compendium of Project Summaries

The project summaries are organized by Capability Pillar – Complex Natural and Engineered Systems, Information Science and Technology, Materials for the Future, Nuclear and Particle Futures, Science of Signatures, and Weapons Systems. Project summaries for continuing projects appear first, followed by project summaries and technical outcomes for projects that ended in FY23.

Hidden in Plain Sight How Interior Furnishings Management Can Help Los Alamos National Laboratory Meet the United States Department of Energy's Sustainability Goals [Slides]

Annually close to 50,000 lbs. of furniture avoids landfills through this program. Over a ten year (2020-2030) over 224 tons of furniture will avoid landfills through the program, that is the weight of the Statue of Liberty. The ReUse program saves LANL $\$172,875$ annually based on the salvage value of the furniture. If the product reused were to be purchased new, LANL would spen close to $1,200,000.

Los Alamos National Laboratory Director's Strategic Resilience Initiative

The Director’s Strategic Resilience Initiative was created late in 2019 in recognition of the changing geo-political climate. The renewed strategic competition between Russia, China, and the United States, noted in the 2018 National Defense Strategy and the 2018 Nuclear Posture Review, put great power rivalry and competition at the forefront of national security considerations. At the same time, Russian President Vladimir Putin’s March 1, 2018, speech and China’s October 1, 2019, National Day Military Parade, underscored the nuclear dimensions of this new strategic competition. Accompanying this changed strategic environment are rapid advances in an expansive array of relevant technological sectors including affordable and comprehensive global communication and reconnaissance assets, autonomous vehicles, quantum computing, advanced manufacturing, and artificial intelligence.

Hidden in Plain Sight: How Interior Furnishings Management Can Help Los Alamos National Laboratory Meet the United States Department of Energy's Sustainability Goals [Capstone Project]

In the last three years, LANL has purchased over $50 million in new interior products with a focus on sustainable building and high-quality interior furnishings, carpet, and paint. Purchasing interior products that focus on sustainable manufacturing, however, is only the beginning of properly operating and maintaining an interior space over its useable life. Sustainable commercial furniture, if well maintained and warrantied, can last well beyond the accounting depreciation of the asset, ultimately saving taxpayer dollars. Given DOE’s recently announced built environment sustainability goals, now is the time to look at interior products as an important part of the overall sustainability plan for LANL’s green building initiatives. The scope of this thesis provides an environmentally sustainable O&M process for the procurement, use, and proper decommissioning of interior products. The thesis also provides environmental and financial data to assist with LANL’s overall DOE Matrix milestones, currently due in 2030.
