Status of the CosmoLep project
1997
The C osmo L ep project was proposed as an experiment to look for coincidences between the four L ep detectors, caused by cosmic ray events larger than conventional extensive air showers. Currently a pilot experiment is in operation, which is using the A leph hadron calorimeter and several scintillator arrays in and near the A leph cavern.
Testbeam studies of production modules of the ATLAS Tile Calorimeter
2009
We report test beam studies of {11\,\%} of the production ATLAS Tile Calorimeter modules. The modules were equipped with production front-end electronics and all the calibration systems planned for the final detector. The studies used muon, electron and hadron beams ranging in energy from 3~GeV to 350~GeV. Two independent studies showed that the light yield of the calorimeter was $\sim 70$~pe/GeV, exceeding the design goal by {40\,\%}. Electron beams provided a calibration of the modules at the electromagnetic energy scale. Over 200~calorimeter cells the variation of the response was {2.4\,\%}. The linearity with energy was also measured. Muon beams provided an intercalibration of the respo…
