Measurement of the ATLAS Tile Calorimeter pulse-shapes with √s = 7 TeV collision data
2010 (English)Report (Other academic)
The energy reconstruction of the ATLAS Tile Calorimeter requires a predefined pulse-shape function. This pulse-shape function must match the pulse-shapes in data to avoid bias in the reconstructed energy. Using 60 nb-1 of √s = 7 TeV collision data, this note investigates deviations between measured pulse-shapes and the pulse-shape used for reconstruction and the possible bias on the energy reconstruction are studied. Measured pulse-shape widths exhibit slight channel-by-channel variations of the order ±1% with respect to the width of the reference pulse-shape. This implies less than 0.5% bias on the reconstructed energy. No energy dependence of the pulse-shapes is found.
