Princeton Plasma Physics Laboratory (PPPL) commissioned us to design and produce this 180-page report identifying critical diagnostics and measurement technologies needed to advance U.S. leadership in fusion energy and plasma technologies. We collaborated directly with PPPL’s Communication Department and leading scientists with content shaping, art direction, design and production of the report and executive summary. The report was produced as part of the DOE’s 2024 Basic Research Needs Workshop on Measurement Innovation, sponsored by the DOE’s Office of Science’s Fusion Energy Sciences (FES) program and guided by FESAC-aligned efforts, to outline critical diagnostic and measurement advancements needed for commercial fusion energy and plasma science.
