Abstract

This document focuses on the design of the system and assembly procedure of the components that will form part of the mechanical structure that will accommodate the new on-detector electronics of the Compact Muon Solenoid (CMS) drift tubes chambers, needed to allow the detector to operate after the upgrade of CERN's Large Hadron Collider to high-luminosity. A study of the context and the current system has been carried out to ensure correct integration. The design has followed an iterative process establishing the required specifications, the study of possible solutions and their adaptability to industrial manufacturing. The analysis of the electronics cooling systems and the importance of materials selection based on component durability under radiation are highlighted. Two assembly sequences have been developed to ensure correct and safe assembly, aiming to optimize work, meet established production timelines and facilitate communication among the different institutions collaborating in the project. Two manuals have been created to guide the operator in the assembly procedure. This document deals with the technical aspects of the manufacture and assembly at CIEMAT, a centre involved in the construction of the drift tubes chambers and whose work continues to contribute to strengthening the position of the CMS experiment and its consolidation as a significant advance in the field of particle physics.
