Monte Carlo Studies of the CALICE AHCAL Tiles Gaps and Non-uniformities

TL;DR

This study uses Monte Carlo simulations to evaluate how gaps and non-uniformities in the highly granular CALICE AHCAL calorimeter affect energy resolution, finding minimal impact on hadron shower measurements.

Contribution

It provides a detailed Monte Carlo analysis of tile gaps and non-uniformities in the CALICE AHCAL, demonstrating their limited effect on calorimeter performance.

Findings

Gaps and non-uniformities have negligible impact on energy resolution.

Monte Carlo simulations effectively model tile response variations.

Results support the robustness of the calorimeter design.

Abstract

The CALICE analog HCAL is a highly granular calorimeter, proposed for the International Linear Collider. It is based on scintillator tiles, read out by silicon photomultipliers (SiPMs). The effects of gaps between the calorimeter tiles, as well as the non-uniform response of the tiles, in view of the impact on the energy resolution, are studied in Monte Carlo events. It is shown that these type of effects do not have a significant influence on the measurement of hadron showers.
