James Casey visits South Pole neutrino observatory

CRA graduate student James Casey recently returned from his expedition to the IceCube Observatory in Antarctica. He reports:

The IceCube Neutrino Observatory is a high energy neutrino detector located at the geographic South Pole. IceCube has 5,160 very sensitive photon detectors buried over 1.5 km deep in the clear ice that are used to collect light produced by neutrinos interacting in the ice. The information collected by this detector can be used to study everything from dark matter to exploding stars! I was recently fortunate enough to make a trip to the South Pole where I collected calibration data to help us better characterize the performance of the observatory.
