The TileCal is the hadronic calorimeter covering the most central region of the ATLAS experiment at LHC. It is a sampling calorimeter with iron plates as absorber and plastic scintillating tiles as the active material. The scintillation light produced by the passage of charged particles is transmitted by wavelength shifting fibers to about 10000 photomultiplier tubes (PMTs). Integrated on the...

The CMS ECAL is one of the highest resolution electromagnetic calorimeters ever constructed, but relies upon precision calibration in order to achieve and maintain its design performance. Variations in light collected from the lead tungstate crystals, due to intrinsic differences in crystals/photodetectors, as well as variations with time due to radiation damage for example, need to be taken...

When using detectors made of a crystal and a photo-detector in high rate applications it is not always possible to integrate the whole signal, the integration time being dictated by the need to avoid in the read-out the pile-up due to the large background of low energy particles.
By means of both experimental data on a BGO crystals and simulation, we developed a technique to compute the...
