Description

The Mechanisms for Amplification of fusion Reaction Rates in Solids (MARRS) program aims to advance the fundamental understanding of mechanisms that can increase the rate of nuclear fusion reactions in solids at reaction temperatures at and near room temperature. The program will combine predictive and quantitative theoretical analysis, modeling, and simulations with reproducible experimental demonstrations of nuclear fusion rate increases by several orders of magnitude beyond the state-of-the-art. Some key points to consider: • The MARRS program is sponsored by the Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office (DSO). • A Proposers Day webcast will be held to provide information to potential proposers on the objectives of the anticipated Broad Agency Announcement (BAA). • Teaming is optional but encouraged, and DARPA may help facilitate the formation of teams with the necessary expertise. • The Proposers Day will include Lightning Talks, sidebars, and an opportunity to meet individually with the Program Manager. • Registration for the Proposers Day webcast is required, and advance registration is mandatory for every individual intending to view the webcast.

Budget estimate

$1,000,000 – $10,000,000

The budget for this opportunity is difficult to estimate, as the document does not provide a specific amount. However, considering the scope of the MARRS program and the involvement of DARPA, it is likely that the budget will be substantial. A possible estimate could be in the range of $1 million to $10 million, depending on the specific requirements and goals of the program. Factors that may influence the likely payment range include the complexity of the research, the number of participants, and the duration of the project.
