Pion and Proton Showers in the CALICE Scintillator-Steel Analogue Hadron Calorimeter

Abstract

Showers produced by positive hadrons in the highly granular CALICE scintillator-steel analogue hadronic calorimeter were studied. The experimental data were collected at CERN and FNAL for single particles with initial momenta from 10 to 80 GeV/c. The calorimeter response and resolution and spatial characteristics of shower development for proton- and pion-induced showers for test beam data and simulations using Geant4 version 9.6 are compared.
