6 Experimental Requirements

In this section we discuss the requirements on IceCube technologies dictated by science. The most important requirements can be summarized as follows:

• time resolution of ≤ 5 ns rms,
• waveform digitization with ≥ 200 Msps (first 400 ns) and ≥ 33 Msps (thereafter),
• waveform sampling depth of 4 μs,
• dynamic range of ≥ 200 PE/15 ns,
• dead time of ≤ 1%,
• gain variation of ≤ 2% per week,
• OM noise rate ≤ 500 Hz,
• overall permanent channel failure rate of < 5%.

While extensive simulations of the IceCube detector and its performance have been done, ongoing studies of improved analysis techniques using the operating AMANDA-II detector may still suggest changes in these requirements.
