Electronics and CNC milling machine control
Tmej, Tomáš ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
The diploma thesis focuses on the electronics design of a hobby CNC milling machine. There are analysed and described the individual electronic parts and components related to this problematic. Three electronics suggestions are made, these suggestions are compared. Then, one of these variants is selected and implemented. Next, is created a relevant PLC program to control the CNC milling machine with visualization for easy control.

Design of workshop crane with powered chassis
Tmej, Tomáš ; Hadraba, Petr (referee) ; Kočiš, Petr (advisor)
This bachelor’s thesis focuses on design of workshop crane with powered chassis. The work describes available types of cranes and devoted to the category of workshop cranes in detail. Two construction designs of a workshop crane with powered chassis are elaborated. One option is selected. In this selected variant is made a detailed design, control calculations of the supporting parts and the production drawings are drawn at the end.

Measurement of scintillator light yield nonlinearity in the neutrino experiment JUNO
Tměj, Tomáš ; Vorobel, Vít (advisor) ; Krtička, Milan (referee)
In order to be able to determine neutrino mass hierarchy in the neutrino oscillation experiment JUNO we need to understand the dependence of the response of the signal from the scintillator on the deposited energy inside the scintillator. We measure the nonlinearity of the signal response via the Compton scattering inside the scintillator and via the precision gamma spectroscopy inside the HPGe detector. We observe effects of different parameters on the experiment via the Monte Carlo simulations. We also improve the data processing of the measured data and discuss what improvements of the experiment we can use in the future.

Linearity of light yield in JUNO neutrino experiment
Tměj, Tomáš ; Vorobel, Vít (advisor) ; Krtička, Milan (referee)
The aim of the work is measurement of linearity of liquid scintillator light yield. Knowledge of deviation from the light yield linearity is essential for interpretation of the data measured in the neutrino experiment JUNO. The method is based on use of Compton scattering in the tested scintillator and on precise spectroscopy of the scattered gamma radiation.
