Design of Accelerator for Oncological Therapy
Zbořil, Jan ; Siebert, Petr (referee) ; John, David (advisor)
The aim of this diploma thesis is the design of linear accelerator for oncology treatment. The design focuses on the improvement of the aesthethical side of the accelator, but also comes up with inventional solutions how to improve the radiation treatment of oncology patients to higher the chances of successful treatment of cancer.

Structure and properties of electron beam penetration produced in steel AMS 5659
Říčan, Daniel ; Foret, Rudolf (referee) ; Kouřil, Miloslav (advisor)
This master thesis deals with the electron beam welding of the AMS 5659 steel used in industry for special hydraulic cylinders (Fig. 1). A theoretical analysis of electron beam welding and analysis of the influence of selected welding parameters on penetration characteristics are in the first part of the thesis. The second part contains an evaluation of the implemented experimental penetrations on samples of the steel in the hardened condition H1025 and after solution heat. It was also done a properties assessment of the same samples that were been hardened again. The light microscopy (SM), the scanning electron microscopy (SEM) and the measurement method of hardness according to Vickers were used for evaluation and comparison of the steel properties in the region of penetration and the heat affected zones properties.

Analysis of application electron beam in industry
Rudyk, Martin ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
The bachelor´s thesis analyses individual methods of usage electron beam in an industrial practice, as a welding, machining, deposition, heat treatment material and gravure. As well it compares individual application with anologous method of special fusing welding like a laser welding. It describes his benefits and disadvantages, principles of the beam rise, etc. In the thesis a welding equipment, its function, weld metal connections for various materials, weldability of the different materials are described.

Application of magnesium alloys castings
Pernica, Vítězslav ; Liškutín, Petr (referee) ; Roučka, Jaromír (advisor)
Magnesium alloys are still idle in technical applications because of their properties. The history of metal is not very old, the first application of its alloy started on the beginning of the 20th century. Magnesium is very light. Its weight is about one third less than the weight of aluminum and it is the third most frequented structural metal. However its preparation and processing can be problematical because magnesium has high affinity to oxygen. It causes intensive burning. During the century of stature have been improved both production and alloys. The usage of magnesium alloys took more importance and it is the most used alloy in automotive field sofar. Recently its demand expands mainly in electrotechnics. Next usage we can find in aeronautics, energetics, military and many other branches.

Vizualization of impurities in production processes using Recognoil 2W device
Řezníček, Lukáš ; Bača, Petr (referee) ; Chladil, Ladislav (advisor)
This work deals with the detection and visualization of impurities during production processes and on the PCB surface using the Recognoil 2W device. The principle of operation of the Recognoil 2W device is described, as well as other methods and options for detecting dirt. Surface preparation methods and technological processing processes, where emphasis is placed on surface cleanliness. At the end of the work, the technological processes dependent on surface cleanliness and the analysis of PCB surface cleanliness using the ROSE method are processed.

Integration of laser ablation into the workflows of FIB-SEM systems
Valenta, Jakub ; Adámek, Martin (referee) ; Búran, Martin (advisor)
Cílem této diplomové práce je ověření vlivu různých nastavení parametrů systému laserové ablace na různé typy mikroelektronických materiálů. Práce má za úkol popsat účel analýzy skrytých defektů v těchto strukturách a způsob jejich řešení. V rámci práce jsou řešeny principy funkce obráběcích a zobrazovacích zařízení na úrovni mikro- či nanometrových velikostí struktur. Předmětem zkoumání je především operační rozdíl mezi procesy obrábění pomocí iontového svazku a pomocí laserového paprsku a jeho integrace do oblasti zajištění kvality. Jde o propojení laserových zařízení se systémy iontových a~elektronových svazků. V práci jsou také popsány výsledky experimentů, během kterých byla provedena analýza defektů vybraných struktur.
