Here below you can find a picture of our detectors in Växjö. The picture was taken in January 2019. For the moment we have two large water Cherenkov detectors and several scintillator detectors, and we continuously take data. The signals we see in the detectors are generated by the passage of relativistic particles in water and in oil. These relativistic particles are created in the atmosphere by interactions of cosmic rays with the atoms composing the atmosphere.
