Title: Prototype of detector for detection of reactor's antineutrinos Author: Lukáš Fajt Department: Institute of Particle and Nuclear Physics Supervisor: Doc. Ing. Ivan Štekl, CSc., IEAP, CTU in Prague Abstract: This master thesis is related to the development of the complex detector of reac- tor's antineutrinos, so called S3 , which is based on the polystyrene scintillation detectors. The detector S3 (dimensions 40 x 40 x 40 cm3 ) will be located in the close vicinity of a nuclear reactor (5-12 m) and its purpose will be to measure reactor's power, isotopic composition of the nuclear fuel and moreover verification of the sterile neutrino hypothesis by detecting reactor's antineutrinos via the Inverse Beta Decay (IBD) interaction. Within the thesis, the first prototype of the antineutrino detector was constructed. It is composed of 18 scintillation plates (40 x 20 x 1 cm3 ) and corresponding electronics. With this prototype the first test with cosmic muons were performed. Within the thesis, the energy reso- lution of the scintillation plates was significantly improved by the optimization of their chemical composition and selection of the optimal refractive material. The proper energy resolution is very important for the detector functionality. In addition, a new methods for the production of coating layer...

Validation of silicon detector simulations for the Belle II experiment
Fajt, Lukáš ; Kvasnička, Peter (advisor) ; Drásal, Zbyněk (referee)
Title: Validation of silicon detector simulations in the Belle II experiment Author: Lukáš Fajt Department: Institute of Particle and Nuclear Physics Supervisor: RNDr. Peter Kvasnička, Institute of Particle and Nuclear Physics Abstract: This bachelor thesis deals with testing of simulations for planned combined Belle II PXD and SVD testbeam at DESY, Germany. This testbeam is going to study the function of a setup of six detectors, two DEPFET pixel detectors and four strip detectors, which corresponds to the actual arrangement of the internal detector of the newly built experiment Belle II in KEK, Japan. For the purpose of testing a new module in the basf2 Belle II software framework was developed. This module should also be used in the future for analysis of experimental data from the testbeam and to compare the results with simulations. In addition to the theoretical knowledge about the Belle II experiment, silicon detectors and basf2, experience with experi- mental work in the clean room at IPNP was obtained. The theoretical part of this work reviews the physical motivation of the experiment as well as the arrangement and operation of the Belle II detector. In the second part we discuss silli- con detectors with an emphasis on DEPFET detectors. We then describe the Belle II software framework, basf2,...
