This work presents the design of an optical link card developed in the frame of the R&D activities for the phase 2 upgrade of the TileCal experiment as part of the evaluation of different technologies for the final choice in the next two years. The board is designed as a mezzanine which can work independently or plugged in the Optical Multiplexer Board of the TileCal backend electronics. It includes...
We present an Optimal Filtering (OF) algorithm to reconstruct the energy, time and pedestal of a photomultiplier signal from its digital samples. The OF algorithm was first developed for liquid ionization calorimeters, its implementation in scintillator calorimeters, specifically in the ATLAS hadronic Tile calorimeter (TileCal), is the aim of this study. The objective is to implement the algorithm...
We present an algorithm to reconstruct online the energy in the TiCal detector of ATLAS. The algorithm consists in weighted sums of the digital samples of the photomultiplier signal. The weights are calculated to reconstruct the desired parameters of the signal while minimizing the noise impact on the resolution. The algorithm has been satisfactorily tested in two types of data, data obtained with...
