CALICE Si/W ECAL: Endcap structures and cooling system

TL;DR

This paper discusses the design and testing of the endcap structures and cooling systems for the CALICE Si/W electromagnetic calorimeter, a key component for the future International Linear Collider's detector system.

Contribution

It presents the design, testing, and integration efforts for the endcap mechanics and cooling systems of the CALICE Si/W ECAL for the ILD detector at the ILC.

Findings

Successful prototype testing of endcap structures

Effective cooling system designs validated

Integration procedures established for detector assembly

Abstract

The next major project of particle physics will be the International Linear Collider: a linear accelerator in which electrons and positrons will collide with energies of 500 to around 1000 billion electronvolts. The LPSC-Grenoble is involved in the R\&D activities for the International Large Detector (ILD) and in particular in the electromagnetic calorimeter (ECal): i.e. design of the fastening and cooling systems, design of the mechanics of the end-caps, test of EM prototypes, tooling and integration of the end-caps.
