Paper Abstract

The Pierre Auger Project is an international effort to make a high statistics study of cosmic rays at the highest energies. To obtain full sky coverage two nearly identical air shower detectors will be constructed, one to be placed in the Northern Hemisphere and one in the Southern Hemisphere. Each installation will have an array of about 1,600 particle detectors spread over 3,000 km2. Atmospheric fluorescence telescopes placed within and on the boundaries of the surface array will record showers that strike the array. The two air shower detector techniques working together form a powerful, hybrid, instrument for these studies. The results from both air fluorescence and surface detectors, on their own, have been quite notable, but are also notable in their disagreement with each other. Hence the concept of an experiment unifying the two approaches to the highest-energy cosmic rays. It is the design of the hybrid nature of the experiment, the analysis of events with hybrid information, and some preliminary results that will be discussed here.
