Why measure cosmic radiation with a three-tonne block of ice on an icebreaker?
... ice block measures 2 m in diameter and 1 m in height. The ice has been frozen in such a way that no bubbles form, making it extremely clear, and each ice block contains two light detectors. We can use IceTop to measure variations in the ...
