The Tile hadronic calorimeter (Tilecal) is a part of the ATLAS detector planned for the LHC accelerator. This calorimeter consists of alternating layers of steel (absorber) and scintillator (active medium). Light produced in scintillator is guided by optical fibres to photomultipliers (see figure).

Members and PhD students of IPNP participating in this experiment:

• Tomáš Davídek
• Jirí Dolejší
• Zdenek Dolezal
• Petra Krivková
• Rupert Leitner
• Karel Soustruzník
• Michal Suk
• Petr Tas
• Zbyšek Trka
• Štefan Valkár

Complete information can be found on the official home page at CERN. Currently we are mirroring the Tilecal notes from the CERN library server:

• Tilecal internal notes

Apart from the analysis of the calorimeter modules beam test data and MC simulation, the Prague Tilecal group members participate in other activities:

• Construction of calorimeter submodules: 300 Tilecal submodules will be constructed in Prague during 2 years. Moreover, all steel absorbers for the whole calorimeter (almost 3000 tons) were produced in Czech Republic.
• Lightmixer production

• Construction and tests  of high voltage supplies

Other usefull information concerning the on-going work in Prague Tilecal group can found on the WWW server at Institute of Physics, Academy of Sciences.

  On the ATLAS plenary meeting, held on 20.11.1997 at CERN, Rupert Leitner presented the summary on experimental results obtained at the SPS beam tests with the Tilecal prototype modules. The presentation Module 0 project report was grafically prepared by Petra Krivkova.
