BeamNetUS: Accelerating Beam-Based Research

BeamNetUS is a collaborative network of twelve beam test facilities spanning six U.S. Department of Energy national laboratories, dedicated to advancing particle accelerator research, technology development, and applications. Through an annual open call for proposals, BeamNetUS invites exploratory research aimed at seeding new collaborations and fostering innovation across the accelerator community. Users gain access to state-of-the-art experimental capabilities, specialized expertise, and a diverse suite of distributed resources. The pilot run in Fiscal Year 2025 supported a broad range of experimental awards encompassing materials science, photon source and accelerator component R&D, plasma physics, and beam diagnostics and control, including studies leveraging artificial intelligence and machine learning. In Fiscal Year 2026, three additional facilities joined BeamNetUS, further expanding the network's reach and enhancing its already broad portfolio of research and development opportunities. This contribution provides an overview of the BeamNetUS program and highlights its recent progress, achievements, and future outlook.
