Monte-Carlo simulation of photodissociation spectra from molecular beam experiment
Košťál, Pavel ; Fárník, Michal (advisor) ; Havlíček, Josef (referee)
Within the framework of my BSc Thesis I became familiar with a unique molecular beam apparatus for cluster studies. I have learned about clusters and molecular beams, mass spectrometry, photodissociation and molecular dynamics. My specific task was to generace several computer programs for data acquisition and evaluation of~the~present experiments: (1) A program for TOF to mass spectra conversion. This program facilitated immediate evaluation of~the~measured mass spectra. (2) A program for TOF spectra conversion into the kinetic energy distribution KED of the fragments, which provides immediate information about the studied photochemical processes. The immediate information provided by both these programs enable a more effective control of the experiment. (3) Finally, I have modified Monte-Carlo simulation program. This program serves the ultimate TOF→ KED conversion of the experimental data. All the programs were tested with photodissociation of a well studied system of HBr cluster, and they have shown a good performance.

Concept of Purity in Jewish sources and in Jesus' teaching as the background of Mark 7
Košťál, Pavel ; Brož, Jaroslav (advisor) ; Scarano, Angelo (referee)
Pavel Košťál Concept of Purity in Jewish Sources and in Jesus' Teaching as the Background of Mark 7 Annotation This diploma work is discussing the main sources of Rabbinic teaching on purity and comparing them with the new priniciples of religious purity in Jesus' teaching. The conflict of these two religious concepts is presented in the Gospel of Mark, chap. 7, which serves in this work as the main reference text. Key words: - purity - inner purity - outer purity - blemishing - hands unwashed - hands unwashed - body - heart

Ion imaging method in molecular beam photodissociation experiments
Košťál, Pavel ; Fárník, Michal (advisor) ; Roučka, Štěpán (referee)
During my master thesis I became familiar with ion imaging and velocity map imaging (VMI) techniques in experiments with molecular beam. My major contribution was writing a computer program for data acquisition and pre-analysis. The program features initial filtering of the data, improving significantly signal to noise ratio. Non-trivial effort was required to make the program compatible with three different CCD cameras implemented on different experiments in the laboratory. I have also simulated ion trajectories in VMI and wrote a program code to imulate VMI image distortions due to imperfections in apparatus geometry. These programs will be useful in aligning and tuning the apparatus. Finally, I wrote a program for data manipulation and conversion to formats compatible with various data analysis programs available in the laboratory. All the above programs I have tested by measurements of 243 nm photodissociation of HBr molecules.
