Performance of the Pierre Auger Observatory Surface Detector

Understand

The Surface Detector of the Pierre Auger Observatory will consist of 1600 water Cherenkov tanks sampling ground particles of air showers produced by energetic cosmic rays.

• The arrival times are obtained from GPS and power is provided by solar panels.
• The construction of the array is nearly completed and a large number of detectors has been operational for more than three years.
• In this paper the performance of different components of the detectors are discussed.
