Construction Strategy
• Maximize the amount of IceCube instrumentation that can be safely installed at the South Pole in each austral summer season
– Installation should not be limited by the availability of instrumentation– Critical path is the drilling of holes
• Construction schedule constraints:– South Pole construction season limited to the austral summer and often impacted by weather conditions– Limits on the number of flights to the Pole (cargo space)– Limit on the number of people that can be supported at the pole

One year of experience with the first IceCube string
String deployment speed reached expectations
Verifications of the new IceCube strings in progress
More PMT-cathode area in IceCube than in AMANDA
Deployed IceCube strings already larger than AMANDA
IceCube on track towards a 1 km3 neutrino telescope!
