(PhysOrg.com) -- ARIANNA, a proposed array of detectors for capturing the most energetic cosmic rays, is being tested in Antarctica with a prototype station built last December on the Ross Ice Shelf by a Berkeley Lab team. By detecting neutrino-generated signals bounced off the interface of water and ice beneath the shelf, scientists hope to pinpoint the still unidentified sources of ultra-high-energy cosmic rays.
