What is Los Alamos System

Los Alamos National Laboratory's mission is to solve national security challenges through scientific excellence.[25] The laboratory's strategic plan reflects U.S. priorities spanning nuclear security, intelligence, defense, emergency response, nonproliferation, counterterrorism, energy security, emerging threats, and environmental management. This strategy is aligned with priorities set by the Department of Energy (DOE), the National Nuclear Security Administration (NNSA), and national strategy guidance documents, such as the Nuclear Posture Review, the National Security Strategy, and the Blueprint for a Secure Energy Future

Los Alamos is the senior laboratory in the DOE system, and executes work in all areas of the DOE mission: national security, science, energy, and environmental management.[26] The laboratory also performs work for the Department of Defense (DoD), Intelligence Community (IC), and Department of Homeland Security (DHS), among others. The laboratory's multidisciplinary scientific capabilities and activities are organized into four Science Pillars:[27]

The Information, Science, and Technology Pillar leverages advances in theory, algorithms, and the exponential growth of high-performance computing to accelerate the integrative and predictive capability of the scientific method.

The Materials for the Future Pillar seeks to optimize materials for national security applications by predicting and controlling their performance and functionality through discovery science and engineering.

The Nuclear and Particle Futures Pillar applies science and technology to intransigent problems of system identification and characterization in areas of global security, nuclear defense, energy, and health.

The Science of Signatures Pillar integrates nuclear experiments, theory, and simulation to understand and engineer complex nuclear phenomena.
