Eligibility details from the notice
Track 1: Accelerator Stewardship Topical Areas Applications for activities in Track 1: Accelerator Stewardship Topical Areas will be accepted from all responsible domestic organizations capable of meeting the objectives of this NOFO. Track 2: Collaborative Accelerator Research Teams (CARTs) for Long-Term Generic Accelerator Research Applications for terminal renewal awards under Track 2: Collaborative Accelerator Research Teams (CARTs) for Long-Term Generic Accelerator Research are restricted to Track 2 PIs organizations with a current award that ends before September 30, 2026. Eligibility is limited in Track 2 to current PIs at organizations with awards expiring within FY 2026 while Track 2 changes from a single-PI/single-institution funding model to a multi-PI/multi-institution funding model. The one-year-long terminal renewal award is offered to allow a smooth transition to other funding sources (which might include participating in a multi-PI/multi-institution award). Track 4b: Accelerator Technology Partnerships Eligibility is limited in Track 4b to domestic for-profit organizations, as the intent of this Track is to develop U.S. companies capable of producing particle accelerator components for DOE and commercial purposes. Track 3 and Track 4a: Track 3 (Accelerator Stewardship Test Facility Program) and Track 4a (Accelerator-Technology Sector Business Plans) are no longer accepting applications.
