Design of the SHiP Electromagnetic Calorimeter — •Claudia Caterina Delogu, Sebastian Ritter, and Matei Climescu — Johannes Gutenberg Universität Mainz

The SHiP (Search for Hidden Particles) experiment is designed to explore feebly interacting particles at the GeV scale at the CERN SPS beam dump facility. Central to the SHiP detector is its electromagnetic calorimeter, which is responsible for energy measurements, particle identification, and reconstruction of neutral particle directions (pointing capability).

This presentation will detail the design of the SHiP calorimeter: a modular sampling calorimeter made of iron and plastic scintillators, read out by Silicon Photomultipliers. The calorimeter is optimized to meet SHiP requirements for energy resolution and angular reconstruction. We will discuss the considerations that contribute to the design, particularly the geometric layout, and the construction of the first prototype.
