Researchers seek ghost-like particles deep in Lake Superior

Key Points:

• Researchers are installing five three-story metal towers equipped with photosensors in Lake Superior near Two Harbors to detect neutrinos, elusive particles emitted from an accelerator near Chicago every 1.2 seconds.
• This project aims to be the first to detect artificial neutrinos in water by capturing the faint blue light emitted when neutrinos interact with atoms in water, advancing understanding of these fundamental but hard-to-detect particles.
• Sponsored by DARPA, the research has potential defense applications such as monitoring nuclear reactors or submarines, though officials emphasize the project remains open to various possibilities without focusing on a specific use.
• The installation involves collaboration among the University of Minnesota Duluth, the Department of Energy, Brookhaven National Laboratory, and others, with support from Woods Hole Oceanographic Institute's research vessel Neil Armstrong for precise placement and fiber optic connectivity.
• The effort builds on previous neutrino detection experiments, including those in underground mines and the IceCube Neutrino Observatory in Antarctica, highlighting growing scientific interest exemplified by the recent Nobel Prize awarded for neutrino research.
