Simulation and Tests of Strip Semiconductor Detectors for ATLAS Upgrade
Theiner, Ondřej ; Kodyš, Peter (advisor) ; Řezníček, Pavel (referee)
Together with the ongoing works on preparations of High-Luminosity LHC, there is a need to enhance the performance of various experiments on the collider as well. This is also the case of the experiment ATLAS and its subdetectors such as Inner Detector which will be completely replaced by new all-silicon Inner Tracker (ITk). This thesis deals with computer simulations of silicon strip detec- tors for ATLAS Upgrade ITk. For this purpose, we are using framework AllPix2 . It enables to simulate everything from the interaction of the particle with silicon, charge propagation in electric and magnetic fields, charge collection, up to signal digitization. We focused mostly on three aspects in the simulations. The first is a precise characterization of used detectors, the second is a simulation of a test beam measurements and the third one is a simulation of test measurements with a radioactive beta source. We also discussed the possibility of simulation of test measurements with a laser. These simulations are important not only because they help us to better understand processes happening inside the detector, but they are also used as a validation of testing measurements. As a result of this, we are able to point out the effects of the experimental setup (or detector itself) which have an impact on measured...
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.
