TL;DR

Scientists have proposed that future fusion reactors—built to generate clean energy—might also produce and help detect dark matter particles (like axions) because of the huge neutron flux hitting the reactor walls, a mechanism not previously exploited. If confirmed, fusion plants could double as dark matter research facilities, helping answer one of physics’ biggest puzzles. (ScienceBlog.com)

Key Points

• Dark matter mystery: Dark matter makes up the bulk of matter in the universe but has never been detected directly; axions are among the leading theoretical candidates. (ScienceDaily)

• Fusion reactors as particle sources: In deuterium–tritium fusion, most energy is released as high-energy neutrons. These neutrons hitting the reactor walls could produce rare particles (including axions) via nuclear processes. (ScienceBlog.com)

• Detection concept: Detectors placed near fusion facilities could capture signals from such particles, potentially probing dark matter interactions beyond current limits. (ScienceBlog.com)

• Real breakthrough: Physicists at UC, Fermilab, MIT, and Technion have now outlined the theoretical basis for this possibility—solving a problem even fictional scientists struggled with on The Big Bang Theory. (Phys.org)
