Energy resolution of the AHCAL and comparison of electron data with simulation. — •Amine Elkhalii for the CALICE-D collaboration — Bergische Universität Wuppertal
The CALICE Collaboration develops calorimeters for a future e+e− linear collider. Theses calorimeters have a high granularity in order to allow Particle Flow Analysis and to achieve high jet energy resolutions of 3−4 %. One of these concepts is the Analog Hadronic Calorimeter (AHCAL), which is based on 3*3 cm2 scintillator tiles with individual Silicon Photomultiplier readout. A large technological prototype of 38 layers with 1.7 cm steel absorber (∼ 4 λ ) has been constructed and commissioned by several institutes. The prototype has been installed in H2 beam line at the CERN SPS, where the test beam has been performed during two periods May and June 2018. Around 8 to 10 *107 events from muon, electron and pion has been collected with different energy ranges. Comparing the longitudinal electron shower profiles data with simulation is one of the important study for the calibration and performance of the detector. This talk will focus on energy resolution of the AHCAL and comparison of electron data with simulation.
