AMIGA - Auger Muons and Infill for the Ground Array of the Pierre Auger Observatory
PIERRE AUGER COLLABORATION (J. ABRAHAM, ... , A. MARIAZZI, ET AL)
Conferencia; 31th International Cosmic Ray Conference; 2009
AMIGA consists of 85 detector pairs eachone composed of a surface water-Cherenkov detectorand a buried muon counter. Each muon counterhas an area of 30 m2 and is made of scintillatorstrips with doped optical fibers glued to them, whichguide the light to 64 pixel photomultiplier tubes.The detector pairs are arranged at 433 and 750 marray spacings in order to perform a detailed studyof the 1017 eV to 1019 eV spectrum region. Designparameters and performance requisites are outlined.Construction of the first muon detectors, associatedsoftware and hardware, and the results of laboratorytests are described. Some preliminary results on theperformance of the 750 m array of surface detectorsare presented.
