Measurement of the average depth of shower maximum and its fluctuations with the Pierre Auger Observatory

PIERRE AUGER COLLABORATION (J. ABRAHAM, ... , A. MARIAZZI, ET AL)

Conferencia; 31th International Cosmic Ray Conference; 2009

The atmospheric depth Xmax where an air shower reaches its maximum size is measured shower-by-shower with a resolution of 20 g cm−2 onaverage using the air fluorescence telescopes of thePierre Auger Observatory. The mean value Xmax and the RMS width of the Xmax distribution will be reported for 13 different logarithmic energy intervalsabove 1 EeV.
