pages 244 - +7p., full text

The Pierre Auger Observatory is designed for study of the universe´s highest energy showers, witch evolve in high layers of atmosphere, where an elementary particle strike with energy above 1019 eV . One of the detection technique of this showers is to observe it by fluorescent detectors, which are able to record the cascade development where the secondary particle cause atmospheric nitrogen to fluoresce. This detectors are optical telescopes, mirror in the each of them is composes of 60 hexagonal ultra-thin segments. An example and result of tilt-dependence analysis of this segments in gravitational field of the Earth are here presented.
