The Pierre Auger Observatory currently under construction in Argentina will
investigate extensive air showers at energies above 10^18 eV. It
consists of a ground array of 1600 Cherenkov water detectors and 24
fluorescence telescopes to discover the nature and origin of cosmic rays
at these ultra-high energies.
The ground array is overlooked by 4 different fluorescence buildings which are
equipped with 6 telescopes each. An independent local data acquisition (DAQ) is
running in each building to readout 480 channels per telescope. In addition, a
central DAQ merges data coming from the water detectors and all fluorescence
buildings.
The system architecture follows the object oriented paradigm and has been
implemented using several of the most widespread open source tools for
interprocess communication, data storage and user interfaces.
Each local DAQ is connected with further sub-systems for calibration,
for monitoring of atmospheric parameters and slow control. The latter is
responsible for general safety functions and the experiment control.
After a prototype phase to validate the system concept the Observatory is
taking data in the final setup since September 2003. The data taking will
continue during the construction phase and the integration of all sub-systems.
We present the design and the present status of the system currently running
in two different buildings with a total of 8 telescopes installed.
