Influence of working conditions on the results of X-ray analysis in the low vacuum scanning electron microscope
Hudzik, Martin ; Zimáková, Jana (referee) ; Čudek, Pavel (advisor)
Bachelor’s thesis deals with detection of characteristic X-Ray and energy dispersive spectroscopy in the environment of low vacuum scanning electron microscope. Describes the detection of X-Ray by silicon drifted detector and also describes the principles of qualitative and quantitative X-Ray analysis. The objective of this thesis is to perform energy dispersive spectroscopy of known elements under the optimal conditions and to monitor changes of parameters and results of the spectroscopy during the change of working conditions in low vacuum scanning electron microscope Vega3 XMU with Xflash 6|10 spectroscope.

Influence of working conditions on results of EDS analysis in environmental SEM
Kaplenko, Oleksii ; Chladil, Ladislav (referee) ; Čudek, Pavel (advisor)
The bachelor thesis contains an operating principle of the environmental scanning electron microscope (ESEM), issue of detection of characteristic X-Ray by using an energy dispersive spectroscopy method. The work describes detection of X-rays through silicon drifted detector, and also the principle of qualitative and quantitative X-ray microanalysis. The aim of this work is to study the influence of working conditions in the scanning electron microscope VEGA3 XMU equipped with Xflash 6 | 10 spectroscope on the results of X-ray microanalysis and their evaluations.

Analysis of active material for batteries by EDS
Vídeňský, Ondřej ; Jaššo, Kamil (referee) ; Čudek, Pavel (advisor)
This master thesis deals with analysis of battery mass using x-ray spectral microanalysis. For the measurement two scanning electron microscopes equipped with energy dispersive x-ray spectroscopes were used. Appropriate examples were prepaired by standard method. Then elemental analysis was performed with changing conditions of measurement. Two programs were used for spectrums evaluation and in the end the size of errors was observed for every conditions.

Summary report of results of the contract research between FZU AV ČR, v.v. i. and HVM Plasma s.r.o. for 2016
Mates, Tomáš ; Fejfar, Antonín ; Ledinský, Martin ; Vetushka, Aliaksi ; Pikna, Peter ; Bauerová, Pavla
Samples of protective layers based on DLC (Diamond-like-Carbon) on different substrates (test bodies and real components) were studied by several diagnostic methods.\nRaman spectroscopy was used for the detection of bindings in order to specify the structural variations, surface modifications both for as-deposited samples and particularly for samples that underwent different stress tests.\nScanning Electron Microscope (SEM) was used to examine the surface structure of layers in different locations on the sample and to search suitable test spots for the subsequent analysis by the Atomic Force Microscope (AFM). AFM in special modes was employed to measure the maps local mechanical properties (friction, tip adhesion, energy dissipation, etc.).\nOn a selected sample, the cross-sectional structure of the sample was analysed by the Focussed Ion Beam (FIB) and the elemental composition in various thicknesses was documented by the Energy-dispersive X-ray Spectroscopy (EDS).\n
