Design and Performance of the Lead-concrete Geiger Tower Array within the Hegra Experiment
نویسنده
چکیده
The HEGRA experiment is a hybrid installation characterized by four diierent types of detectors (scintillator counters, open Cerenkov counters, Cerenkov telescopes and Geiger towers) located within one detector array. The Geiger towers are built with the objective to measure the local energy deposition and to reconstruct and identify muon tracks. In addition each tower may serve as an independent high resolution muon ux monitor. With these properties the Geiger towers are operating as geometric and energetic calibration instruments for the other detector components and as additional independent measurement instruments with respect to the-hadron separation and the measurement of the chemical composition. In this paper the design, the performance, and the basic principles of the data analysis of the lead-concrete Geiger towers are described.

Neural Networks for /hadron-separation with the Hegra Geiger Towers 1
Due to the large amount of data and the complexity of the information , analysis of the HEGRA Geiger tower data is based on neural networks (NN). We explain the NN training and the principal characteristics of the analysis and describe rst applications to experimental data, yielding an upper limit on the combined-ray ux above 50 TeV of 16 nearby northern blazars.
