Contribution

It provides a comparative analysis of dead zone effects in different calorimeter geometries, informing optimal mechanical design for the SiD detector.

Findings

Dead zones significantly affect calorimeter response.

Projective geometry shows different crack effects compared to non-projective.

Design recommendations for minimizing dead zone impact.

Abstract

The aim of this study is to find an optimal mechanical design of the hadronic calorimeter for SiD detector which takes into account engineering as well as physics requirements. The study focuses on the crack effects between two modules for various barrel mechanical design on calorimeter response. The impact of different size of the supporting stringers and dead areas in an active calorimeter layer along the module boundary has been studied for single pions and muons. The emphasis has been put on the comparison of the projective and non-projective barrel geometry for SiD hadronic calorimeter.
