First T3B Results - Initial Study of the Time of First Hit in a Scintillator-Tungsten HCAL

We present the first study of the time structure of hadronic showers in the CALICE scintillator-tungsten sampling calorimeter by measuring the time of the first hit in a special timing layer, the T3B setup, about $4 \lambda_I$ deep in the calorimeter. This preliminary study, performed on incompletel...

description We present the first study of the time structure of hadronic showers in the CALICE scintillator-tungsten sampling calorimeter by measuring the time of the first hit in a special timing layer, the T3B setup, about $4 \lambda_I$ deep in the calorimeter. This preliminary study, performed on incompletely calibrated data, is compared to Geant4 simulations and shows very good agreement between data and simulations for a model that includes high precision neutron tracking, while large discrepancies are observed for simulations without this component.
