Noise Hits/event:
Noise hits per event = ( #Optical Modules) x (noise rate) x (readout window)
noise rate: ~200 Hz PMT limit
500 Hz IceCube Proposal
1000 Hz IceCube worst case (moderate radioactivity components)
readout window: 8 microseconds IceCube Proposal
30 microseconds IceCube worst case (trigger jitter and no on-line calibration)
360 OMs _ 0.6-11 hits/evt. IceCube Proposal# 1.4
5000 Oms _ 8-150 hits/evt IceCube Proposal# 20.0
Muon Hits/event:
Local Coincidence trigger (5 LCs) ~12 hits/event on average
IceCube Baseline (simple mult=AMANDA) 22 hits/event on average
The average number of coincident hits in an event will be strongly influenced by the multiplicity of the trigger threshold. The average will be a few hits larger than the threshold.
