UNC physics and astronomy graduate student Grayson Rich (also of the Triangle Universities Nuclear Laboratory) was involved with an experiment involving the world’s smallest neutrino detector.

Science wrote about the “milk jug size” detector which is able to capture neutrinos “in a whole new way.”

After more than a year of operation at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.

The research, performed at ORNL’s Spallation Neutron Source (SNS) and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by theorists 43 years ago, but never seen.
