The IceCube Neutrino Observatory
DeepCore (low energy threshold)
IceTop (surface array): 81 stations
IceCube: 86 strings
5160 optical sensors over 1 km3 volume
17 m vertical spacing
125 m horizontal spacing
Highly stable operation.
- ! No aging from that.
- Need to determine the effect
for every single DOM.
