“Ghostly” neutrinos used for the first time to peer inside protons at Fermilab accelerator

The new technique highlights the importance of being creative and collaborating.

Rochester researchers used a particle accelerator at Fermilab—a portion of which is shown in a stylized image above—to create a beam of neutrinos to investigate the structure of protons. The work was part of the MINERvA experiment, an international collaboration to study neutrinos. Credit: Reidar Hahn/Fermilab.
