Study of Radiation Damage in Silicon Strip Detector for ATLAS ITk
Zatočilová, Iveta ; Mikeštíková, Marcela (advisor) ; Marčišovská, Mária (referee)
Ionizing radiation causes bulk and surface damages in silicon detectors. The significant bulk damage is caused also by neutrons. Those damages in- fluence the detection performance of silicon strip detectors. The main purpose of this thesis is to study the effects of radiation damage in silicon strip sen- sors by performing electrical tests on them. Tested silicon strip sensors were designed for the replacement of the current Inner Detector of the ATLAS ex- periment by a new all-silicon Inner Tracker. This replacement is needed because of the upgrade of the Large Hadron Collider (LHC) into the High-Luminosity LHC. 1

The SCT is a silicon strip detector forming a part of the tracking system of the ATLAS experiment at the LHC. The tracking performance of SCT is influenced by several fundamental effects: multiple scattering, Lorentz drift, energy loss variation, noise occupancy, and δ-ray production. In this thesis, the task requested by the SCT detector group has been performed. Clusters containing a δ-ray, which are assigned to a track were studied on data samples, specially prepared for this purpose. A correction to the affected cluster positions was successfully developed. The correction to δ-rays has been implemented into the ATHENA reconstruction framework and its performance was evaluated. A meaningful usage of correction for the detector alignment has been proposed. The ongoing detailed verification of the performance within the event reconstruction is partially beyond the scope of the thesis work.
