neutrino projects that were under way. The White House was concerned about possible overlap of science goals between IceCube and an underground science laboratory . The 2003 National Research Council report found no substantial overlap between the two projects, noting that they enabled essentially different types of neutrino detection. IceCube is optimized to detect high-energy neutrinos, and the underground science laboratory offers a low-background environment for studying lower-energy neutrinos .
The key IceCube startup activities include development and production of in-ice devices (the photodetectors at the heart of IceCube), development of an enhanced hot-water drill to drill the 2500-m-deep holes in the ice cap into which the photodetectors will be deployed, and data systems development for acquisition, transmission, archiving, and analysis of the data from the roughly 5,000 distinct photosensors in the IceCube array. Drilling and deployment of the IceCube sensors is expected to take six austral summer seasons; completion is estimated in FY 2010.
The president’s FY 2004 budget included funding for IceCube at the level of $295.2 million through FY 2013 . In May 2003, the NSB approved up to $25 million for UW and the USAP to complete the phase 1 effort to develop the hot-water drill and its associated support equipment and to commence developing a design for the downhole electronics modules that operate the photodetectors.
