Hybrid event at Auger




Participants List

The Engineering Array of the Pierre Auger Observatory has been operating in steady fashion since January, 2002. It consists of 30 surface detectors overlooked by two fluorescence telescopes. During this period samples of all the types of events that we expect to observe have been found and many independent  groups have begun to reconstruct them. These include events at zenith angles up to 85 deg, fluorescence events, and hybrid events seen both by the surface array and the fluorescence detector. The purpose of the workshop is to have well defined sets of events reconstructed by at least two independent teams. In addition, we want to compare different calibration techniques for the the surface detectors and the fluorescence telescopes. Finally, we want to compare simulations required to pass from observed signals in the detectors to energies.

The expected outcome will be guidance for the groups preparing production programs. The quantity of data now is small enough that handling the data is not too difficult and one can reconstruct the events with simple programs and deal with complications such as accidental triggers "by hand". When the 1600 tanks will be operating we will expect about 400 events/day with 5 or more tanks triggered. Of these about 200 will be reconstructed. This rate will demand a production program with the sophistication to remove accidentals, correct trigger times from PMT noise or accidental unrelated muons, malfunctioning PMT's, malfunctioning stations etc.

This workshop will not deal with any publishable results. For that we do not have enough events. But we will have enough aperture to do some science in about a year so we want to be ready. Hopefully this workshop will be a step along the way.

At Chicago the Auger Observatory is one of a number of theoretical and experimental activities of the newly formed Center for Cosmological Physics, supported by the NSF. In order to have members of the CfCP as well as other Chicago colleagues become acquainted with Auger we plan to have a CfCP/Enrico Fermi Institute Mini-Symposium on the Auger Observatory on October 4. For schedules and programs follow the links below.
