2 Vanel Jean-Charles LLR / IN2P3 NIKHEF 1-4 April 2003 NIKHEF 1-4 April 2003 General view of the calorimeter Tracker : TPC ECAL : Sandwich Wplate & Si Wafer HCAL : DHCAL or AHCAL Coil : 4 T (2 )

3 Vanel Jean-Charles LLR / IN2P3 NIKHEF 1-4 April 2003 NIKHEF 1-4 April 2003 ECAL concept : - A fine granularity calorimeter with large number of segmentation is proposed as the best solution for the energy flow, lepton identification, photon reconstruction with good precision on energy and direction. - On the other side, the coil thickness is bigger than usual due to the 4 Tesla field needed to maintain the machine background close to the beam pipe. Therefore, the ECAL has to be very compact. (1,30 m for ECAL and HCAL) - Such a calorimeter could be made of Tungsten-Silicon sandwich. -With pad of 1x1 cm and 40 layers : A TRACKER CALORIMETER. -It gives a clean picture of all energy flow objects in all type of events -Simulation using GEANT4 lead to think of an energy resolution on electron/photon in the region of Delta E /E = 11% / sqrt(E)
