TAUP 2003 Project status • Approved by U.S. the National Science Board • Startup funding is allocated. 100 DOMs are produced and being tested this year. • Assembling of the drill/IceTop prototypes is carried out at the pole this season. • Full Construction start in 04/05; takes 6 years to complete. • Then 16 strings per season, increased rate may be possible.
TAUP 2003 GZK EHEn detection • What is the GZK mechanism? • EHE n/m/t Propagation in the Earth • Expected intensities at the IceCube depth • Atmospheric m – background • Event rate
t/mappeared in 10 PeV- EeV are our prime target on GZK n detection. 1/100-1/500 of primary n intensity! Downwardt and m make main contributions in PeV -EeV Energy Estimation would be a key for the bg reduction Because atmospheric m spectrum ~ E3.7 TAUP 2003 Summary GZK n is DETECTABLE by IceCube 0.2-40 events/year (BG 0.05 events/year)
