Expressions of Interest

(Submissions are now closed and intake interviews are underway.)

Pacific Fusion is building a high-yield, pulser-driven inertial fusion facility designed to achieve net facility gain—producing more fusion energy output than total stored energy input—by 2030. It will be the only inertial fusion system of this scale in the world.

Equipped with flexible experimental configurations and 17 diagnostics for fusion target development, the Demonstration System (DS) facility is designed to support Pacific Fusion's work to drive progress across four core areas: Fusion Energy Science, Commercial Applications, Fundamental Science, and National Security (working through the U.S. government).

The Call for Expressions of Interest closed earlier this year. We have notified respondents whether their EOI is moving forward in our process. For those moving forward, intake interviews are now underway and are expected to continue through the end of 2026.

Respondents with questions about their submission or interview scheduling may write to users@pacificfusion.com.

• Early 2027: We plan to convene the first meeting of the Users Program, supporting teaming conversations and joint pursuit of funding opportunities.
• 2027: A formal Call for Proposals will follow the meeting. Information on eligibility, timing, and submission requirements will be posted here and distributed to the mailing list.
  
  

The Call for Expressions of Interest was a commitment-free phase of our planning process. Our goal was twofold:

• Understand potential users’ interests and their associated technical requirements
• Explore potential collaborations with industry, government, and academic partners on our path to commercial fusion
  
  

By participating, you helped define the technical capabilities and diagnostic requirements for the first user experiments later in the decade. This EOI will inform upcoming activities eventually leading to a Call for Proposals.

The online submission form is closed. Organizations interested in using the DS facility may take the following steps.

1. If you missed the original deadline:
   Write to users@pacificfusion.com regarding late submissions or opportunities to collaborate with an existing team. Late submissions may be considered on a case-by-case basis.
2. Sign up for program updates:
   Join our mailing list to receive notice of the 2027 meeting, the Call for Proposals, and updates on facility capabilities.
