Simulations of ATLAS silicon strip detector modules in ATHENA framework

This diploma thesis deals with properties of the silicon strip detector (SCT) modules of the ATLAS detector and building their software model. First part of the thesis consists of a brief overview of the ATLAS detector properties and focuses on the Inner Detector and its SCT part. Besides mechanical characteristics, analysis of capability to measure the charged particle momentum is placed there as well. Main features of the Athena framework and of the entire ATLAS offine software can be found in the further part. Athena framework is developed for simulations and future analyzing of the whole ATLAS measured data. This text is intended mainly for Athena newcomers. The main contribution of this thesis to ATLAS offine software preparation is implementation of the new SCT end-cap modules' geometry model, its detailed checking and preparation of the necessary software component for whole SCT subsystem for the Combined Testbeam (CTB - summer 2004). We perform checking the functionality of the whole simulation sequence from geometry model building and simulation of particle passage through it to processing of the simulated detector response and reconstruction of the particle track.
