Description

We have developed the method of the determination of the absolute energy scale calibration of a single module of the ATLAS TILECAL hadronic calorimeter using the electron and pion beams of energies from 10 to 300 GeV of the CERN SPS. This method has been realized on the basis of the vast exposition of the two extended barrel modules during the test beam period in September 2001. These modules have been exposed at energies E=20, 50, 180 GeV at ±20 and ±90 deg and 1.05<|η|<1.35. The electron and pion calibration constants for the various cells, energies and angles have been extracted. The electron and pion energy resolutions have been studied. The e/h ratios have been obtained. This method has been used for the calibration of TILECAL modules. The obtained calibration constants have been included in the TILECAL calibration database
