Preface

This thesis does not intend to be a handbook for particle physics. Neither does the author want to pretend to understand the unified theory or how the Higgs effect really works. Therefore this topics are mentioned only shortly in the introduction - chapter 1. It will give a brief overview of the ATLAS detector and sub-detectors and more detailed information about the TRT sub-detector and the special design constraints in high-energy physics.

The main part is divided into two parts: signal integrity and electromagnetic compatibility. Chapter 2 analyses the detector in terms of signal integrity by following the path of the signals. It discusses possible solutions and describes the results found by simulations and experiments.

Chapter 3 covers the electromagnetic compatibility of the ATLAS TRT within the system and opposed to a violent environment. It identifies possible noise sources, their receptors, and the coupling paths and describes measures to ensure electromagnetic compatibility. Finally, this chapter presents a grounding scheme of the system.

The conclusions - chapter 4 - discuss the already implemented design solutions and their results. However, the final validation will be available only in 2005 when the full system is running.
