Study of the nuclear mass composition of UHECR with the surface detectors of the Pierre Auger Observatory
PIERRE AUGER COLLABORATION (J. ABRAHAM, ... , A. MARIAZZI, ET AL)
Conferencia; 31th International Cosmic Ray Conference; 2009
We investigate observables that can be measured with the water-Cherenkov detectors of the Pierre Auger Observatory. In particular we explore the use of the risetime of the signals in the detectors and the azimuthal features of the time distributions.A correlation of these observables with the position of shower maximum (Xmax), as measured with the fluorescence telescopes, is obtained.
