In a study published March 26 in Physical Review Letters, collaborators of the MAJORANA DEMONSTRATOR have shown they can shield a sensitive, scalable 44-kilogram germanium detector array from background radioactivity. This accomplishment is critical to developing a much larger future experiment to study the nature of neutrinos.
At 2:45 a.m. on Oct. 6, bleary-eyed Nobel Prize enthusiasts on the West Coast were treated to an unexpected lesson about fundamental particles and forces in our universe. Across the globe in Stockholm, a panel of scientists announced that the 2015 Nobel Prize in Physics would honor two scientists who led international collaborations to understand mysterious particles called neutrinos. The prize recipients, Takaaki Kajita and Arthur McDonald, respectively led the Super-Kamiokande Collaboration in Japan and the Sudbury Neutrino Observatory Collaboration…
