 Agenda for HIAPER Community Workshop in Boulder, Colo., May 1999.
IceCube will be a kilometer-size neutrino detector built in the Antarctic ice. The Antarctic Muon and Neutrino Detector Array (AMANDA) and AMANDA-II demonstrated the feasibility of using the clarity and depth of the ice sheet at the South Pole to detect high-energy neutrinos. See Table C-5 for a timeline of the major developments. With a 1-km3 volume sitting almost 2.5 km below the surface, the world’s largest telescope to date will detect neutrinos traveling through the earth’s core from the northern sky with a pointing accuracy of about 1 degree. Building on the state-of-the-art drilling and detector techniques developed for the earlier projects, IceCube will revolutionize the field of particle astrophysics by allowing the detection of PeV-energy neutrinos . Those neutrinos are believed to result from some of the highest-energy processes observed in the universe, such as gamma-ray bursts and active galactic nuclei. The completion of IceCube will enable us to look deeper than ever before into formation processes and other previously opaque cosmic events.
IceCube was approved by the NSB in October 2000 for submission in a future budget request. MREFC funding was first included in the President’s budget request to Congress in FY 2004. However, Congress provided funding for Ice Cube startup activities in FY 2002 and FY 2003 in the amounts of $15 million and $24.7 million, respectively. The FY 2004 NSF budget request to Congress included $60 million for the start of full construction. Both House and Senate markups have included funding for start of construction, albeit at lower levels than the FY 2004 request. (As of this writing, the conference committee has not met, so the FY 2004 appropriation has not been made.) The total cost of the construction, including the startup funding mentioned above, is projected to be $251.6 million. US funding for the project is provided to the University of Wisconsin-Madison and then to subawardee institutions and to the support contractors of NSF’s US Antarctic Program (USAP)-Raytheon Polar
