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.
