Figure 3.6: Effective muon range as function of its energy[88]France in the Mediterranean sea (Figure 3.9 ) which happens to be the first fullyoperational under sea water neutrino telescope.The detector is located at a depth of 2.5 km in sea water, the telescope standsat a height of 500 m and consists of 12 lines, each line consists of 25 stories. Eachstorey is made up of three optical module and the electronics, each OM containsa PMT (PhotoMultiplier Tube), tilted downward at an angle of 45 ◦ to maximizeupward going Cherenkov tracks. totaling up in 885 OMs (Figure 3.10 ). Each lineis connected to the sea floor via an anchor, and all are connected via electro-opticalcable to the junction box which itself is connected to the offshore station by anidentical electro-optical cable. All these different components will be describedin the next section.The muon detection principle is based on while knowing the precise positionof each OM the track can be reconstructed by knowing the the time differencebetween the different registered hits in the detector (Figure 3.11).40
