Title: Development and application of methods for measurement of magnetic field on tokamaks Author: Ing. Karel Kovařík Department: Department of Surface and Plasma Science, Faculty of Mathematics and Physics, Charles University in Prague Institute of Plasma Physics of the Czech Academy of Sciences, v. v. i. Supervisor: Ing. Ivan Duran, PhD. (Institute of Plasma Physics of the Czech Academy of Sciences, v. v. i.) Abstract: Thesis describes two parts of my work in frame of magnetic confined fusion research. First part describes irradiation testing of the Hall sensors based on InSb semiconductor. It evaluates radiation effects of fast and thermal neutrons on the Hall sensors sensitivity. Tests indicate low level of changes for fluence lower only by order of magnitude than expected in the whole lifetime of ITER tokamak. Second part describes measurement of turbulent plasma structures parameters in scrape--off layer of the COMPASS tokamak, particularly the parallel electric current flowing along them. Design of novel combined probe allowing measurement of not only electrostatic parameters but also the parallel electric current is presented. Evaluation of parallel electric current is discussed and compared with experiment. Statistical analysis of the plasma structures is presented. Empirical formulas of the...

Chapters of the Nuclear Fusion for Secondary Schools
Řehák, Česlav ; Mlynář, Jan (advisor) ; Koupilová, Zdeňka (referee)
Title: Chapters from nuclear fusion for high school education Author: Česlav Řehák Department: Didactics of physics Supervisor: RNDr. Jan Mlynář, Ph.D., Faculty of nuclear physics and engineering, ČVUT Abstract: Text of this thesis is intended for anyone interested in nuclear fusion, although it is especially aimed for education of physics in high schools. The thesis sums up the basic principles of fusion reactions in space and explains it's importance for life on Earth. Additionally, it points out some of the most crucial problems of present world energetics and introduces controlled thermonuclear fusion as a possible solution. The thesis clarifies some of the most important aspects of controlled fusion research, especially the branch of magnetic confinement reactors, and provides the most significant advantages and disadvantages of this potential power source. It also offers variety of illustrative pictures. Keywords: Nuclear fusion, energetics, magnetic confinement, tokamak

Knowledge and Assessment of Nuclear Fusion
Červenka, Jan ; Ďurďovič, Martin
In May 2016 within the survey "Our Society", the annual block of questions on the topic of energy was exceptionally extended for some specific questions. It included questions concerning nuclear fusion as a potential source of energy to which for a long time it is focused attention of research of a number of countries and international groupings.
