Dozens of scientists and engineers across multiple divisions at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) played a role in the design, development, and deployment of the IceCube neutrino sensor array at the South Pole. They pioneered the ice-embedded digital optical modules (DOMs) and circuitry that are IceCube’s key enabling technologies. Berkeley Lab researchers also contributed to a predecessor experiment called AMANDA (the Antarctic Muon and Neutrino Detector Array).
