About Us

The Transport Methods Group (CS-4) creates numerical radiation transport methods to support the United States’ weapons program, and it produces packages for use in Advanced Strategic Computing codes. It develops computational tools that simulate the transport of radiation—charged particles, neutrons, photons, and neutrinos. Applications of these tools range from simulating nuclear reactions to studying the life cycles of stars. Team members have expertise in fields including transport theory, numerical methods, software engineering practices, and large-scale parallel computing.
