König, Vít ; Doležal, Zdeněk (advisor) ; Kvasnička, Peter (referee)
Title: Tests of Silicon detectors for the ATLAS detector upgrade Author: Vít König Department: Institute of Particle and Nuclear Physics Supervisor: doc. RNDr. Zdeněk Doležal, Dr., IPNP Abstract: This thesis is focused on the testing of prototypes of strip silicon detectors for the modernization of ATLAS detector on ATLAS Upgrade. These tests take place at the Department of Silicon Detectors at the Institute of Particle and Nuclear Physics. The main focus of this work is the description of tests of Front-end parameters of the detector using the calibration charge and laser. The first chapter of this thesis briefly describes, how the experiment in particle physics works, and summarizes the basic facts about the ATLAS detector and its upgrading. The second chapter describes the physical properties of semiconductors that are needed to understand the principle of particle detection by silicon detectors. It also describes how to read and process information from the detector. The third and fourth chapters describe the testing of FE parameters of the detector, done itself by the author of this work. Conclusions from these measurements will serve to further tests of strip silicon detectors for ATLAS Upgrade. Keywords: ATLAS Upgrade, laser tests, Front-end elektronic, strip silicon detector

Automation of Semiconductor Detector Tests for ATLAS Upgrade
Martaus, Marek ; Kodyš, Peter (advisor) ; Řezníček, Pavel (referee)
After many years of operation of a Large Hadron Collider, it is necessary to modernize it. The next upgrading will also include an ATLAS detector upgrade. This work is devoted to the development of workflows of testing the silicon strip detectors used in the new ATLAS inner detector. The laser testing method was chosen for the needs of this work. In the first chapters of this work, the reader will learn about the principle of semiconductor detectors, their testing and use in ATLAS. The fourth chapter is devoted to the description of used equipment. The fifth chapter shows the results of the module testing. Discussion of measured results is devoted to chapter six. 1

Tests of Silicon detectors for the ATLAS detector upgrade
Janitorová, Lýdia ; Doležal, Zdeněk (advisor) ; Kvasnička, Peter (referee)
Nowadays, the detector ATLAS is modernized to ATLAS Upgrade. The Insti- tute of Particle and Nuclear Physics contributes to it by testing and production of silicon detection modules, which will be used for this purpose. This thesis is focused on the development of methods of accurate assembling of detection mo- dules, especially to verify that the chips are properly glued to the hybrid using the ConoScan 4000 metrological station. One of the measurement outputs are three coordinates of the corners of the chips. To achieve higher accuracy, instead of determining the coordinate z of the chip relative to the ConoScan reference system, the height was determined relative to the hybrid. For each chip, the angle of rotation was determined in the individual planes. To verify the reproducibility of the measurement by ConoScan, 50 identical measurements of the hybrid profile were scanned, from which the processed results are plotted in histograms. Better results can be achieved by selecting a smaller scanning step of ConoScan along the x and y axes. 1

Tests of Semiconductor Detectors for ATLAS Upgrade
Theiner, Ondřej ; Kodyš, Peter (advisor) ; Řezníček, Pavel (referee)
Together with the planned upgrade of the Large Hadron Collider at CERN, a lot of experiments on the LHC will have to be improved as well. This is also the case of the ATLAS experiment. This thesis focuses on laser testing of silicon strip detectors which will be part of the Inner Tracker in the improved ATLAS Upgrade experiment. The first two parts of the thesis describe the ATLAS Up- grade experiment and summarise the basic theory behind silicon strip detectors. The third and the main part of the thesis is dedicated to experimental part of my work, which consisted of the actual laser testing of silicon strip detectors. The fourth chapter discusses the results of my measurements. All the tests presented in this thesis were performed in the laboratory of the Institute of Particle and Nuclear Physics in Prague. Besides having performed the measurements of de- tection properties of strip detectors, several ROOT macros for automatization of these measurements were written.
