The Pierre Auger Cosmic Ray Observatory is studying ultra-high energy cosmic rays (energy > 10E19 eV). The observatory is located on the vast plain known as the Pampa Amarilla (yellow prairie) in western Argentina. RCPTM produces glass mirror for fluorescence telescopes and Lidars, All Sky cameras for background light monitoring. The employees participate in the observatory operation, measurement of optical properties of fluorescence telescopes and optical elements, data analysis, modeling, design and analysis of optical systems.

Palacky University together with RCPTM actively contributes to CERN activities, in particular in frame of the Forward Detectors subproject within the ATLAS project where we cooperate with international community. The main objective has been development of algorithms and models for data analysis and simulation for the ALFA detector. Nowadays we are going to use our experiences in the oncoming AFP project. Our students participate in physics analysis in area of proton diffraction as for instance hot topic study of exclusive production of pions in proton-proton collisions.
