Muon simulation studies of the CALICE AHCAL 2018 Technological Prototype test beam data — •Saiva Huck for the CALICE-D collaboration — Universität Hamburg, Institut für Experimentalphysik, Luruper Chaussee 149, 22761 Hamburg

The Analog Hadron Calorimeter (AHCAL) is a highly granular hadron calorimeter with 8 million single channels designed by the collaboration Calorimeter for Linear Collider Experiment (CALICE) to be used in a future high precision Particle Flow collider experiment. One single channel is made up of one 30×30×3 mm³ plastic scintillator tile which is read out via one Silicon Photomultiplier (SiPM).

A technological prototype of the AHCAL consisting of 38 active layers alternating with 1.7 cm thick steel absorber plates has been constructed and taken to test beam at the CERN SPS in 2018.

This study focuses on the comparison of characteristics of muon runs used for MIP calibration in both test beam data and the corresponding digitized Geant 4 simulation. Various properties including hit energies and number of hits per event are compared.

Overall, the distributions for the muons in data and simulation are in good agreement which validates the digitization procedure for low deposited energies.
