U of M neutrino detector delivers first 3D image of subatomic particle

The first section of a University of Minnesota particle detector is complete and the facility in Ash River is churning out 3D images of subatomic neutrinos.

Neutrinos have little or no mass, which makes them difficult to study and prompted their nickname "the ghosts of the universe." Physicists say learning about them holds clues to the origins of the universe.

The detector consists of modules that are put together in Minneapolis and shipped to Ash River, which is about 100 miles from Duluth. So far, a 12-foot segment is complete but ultimately the particle detector will be 200 feet long.

While the U of M is leading the effort, researchers from more than 30 universities and institutions are involved in the $283 million project.

The first images come nearly ten years after groundbreaking in Ash River for the facility that expands on research underway in Tower Soudan Mine.

U of M physicists might find Einstein was wrong

Einstein's theory of special relativity says nothing can move faster than the speed of light, but early research suggests that some subatomic particles actually do. Now scientists are trying to confirm that, and one of the few places on Earth where they can conduct such research is in a high-energy physics lab half a mile underground in the Soudan mine up north.
