The FY2026 Research Opportunities in Accelerator Stewardship and Accelerator Development (ARDAP) FOA (DE-FOA-0003620) is the annual competitive grant for research and manufacturing under the DOE Office of Accelerator Research and Development and Production, a program office within DOE Office of Science established in 2020. The ARDAP mission spans two subprograms: research and development, which expands accelerator technology applications through foundational science and provides access to unique DOE accelerator facilities; and production, which advances manufacturing readiness and addresses domestic supply-chain vulnerabilities through technology reshoring. Historical funding under this annual competition was $14.8 million in FY2022 and $11.5 million in FY2024, the latter under the initiative title Particle Accelerators for Science and Society.

Broad eligibility distinguishes ARDAP from most DOE Office of Science FOAs: universities, national laboratories, industry, and other research organizations are all eligible to apply. Individuals cannot apply. No minimum TRL is specified. The FY2026 cycle was posted March 12, 2026, with pre-applications due April 9, 2026, via PAMS, and full applications due May 21, 2026, via Grants.gov. Both of those deadlines have passed, placing the FY2026 cycle in closed status. The FY2027 cycle is expected to open in late 2026 or early 2027, following the standard annual cadence.

Applicants for future cycles should contact the ARDAP program office at sc.ardap@science.doe.gov or 301-903-5475 early in the pre-application planning period. Pre-applications are submitted via the PAMS portal at pamspublic.science.energy.gov; full applications through Grants.gov. Program emphasis on workforce development and supply-chain reshoring makes proposals with a domestic manufacturing or training component particularly well aligned with ARDAP's stated mission.
