On 18 December 2010, the expanded version of AMANDA, IceCube was completed. IceCube works in the same way as AMANDA but on a larger scale. AMANDA was incorporated into IceCube after operating for nine years. IceCube took seven years to complete and measures Cherenkov light emitted by charged particles produced in neutrino interactions in a cubic kilometer of transparent ice – the water equivalent of one million swimming pools.
IceCube detects 275 million cosmic rays each day and approximately 100,000 neutrinos per year. Approximately a terabyte of unfiltered data is collected daily and about 100 gigabytes are sent over satellite for analysis.
