Aperture calculation of the Pierre Auger Observatory surface detector
D. Allard, I. Allekotte, E. Armengaud +11
We determine the instantaneous aperture and integrated exposure of the surface detector of the Pierre Auger Observatory, taking into account the trigger efficiency as a function of…

The trigger system of the Pierre Auger Surface Detector: operation, efficiency and stability
D. Allard, E. Armengaud, I. Allekotte +31
The trigger system of the Surface Detector (SD) of the Pierre Auger Observatory is described, from the identification of candidate showers ( EeV) at the level of a single stat…
