First of all, single charged particle motions, then plasma behavior as fluids, diffusion, and waves in plasmas are explained. For the basic fusion plasma study, magnetohydrodynamics, equilibrium and stability are alsoexplained. Introductions to the kinetic theory and nonlinear effects are performed for advanced studies. |
| Plasma Physics ２ | 2 | Fundamental physics concepts for understanding the characteristic of fusion plasmas which are necessary in the plasma research will be described. Both aspects of the microscopic particle property and the macroscopic fluid property in the plasma behavior will be explained. The contents are composed of motion of a charged particle in various electromagnetic fields, relations between the distribution function in velocity space and the plasma fluid description, magnetohydrodynamic equilibrium and stability, waves in plasmas, basic idea of transport and resistivity and so on. |
| Fundamentals of Plasma Experiment |
2 | The aim of the lecture is to learn error analysis for allowing the scientists to estimate how large his uncertainties are, and to help him to reduce them when necessary. The basics of plasma diagnosis are reviewed. The error analysis based on the mathematical statistics and the least-squares fitting as its application are studied. The normal distribution and other important distributions are treated. |
| Advances in Plasma Science |
2 | The basic physics of plasma transport at the peripheral region and plasma-wall interaction in magnetically confined fusion devices are explained. Especially, the divertor system receives and should handle huge heat flux coming from main plasma. The lecture presents the history of the divertor development and critical issues for next step fusion devices. In addition, the basics of atomic and molecular processes applied in fusion and related plasma researches are given, including atomic and molecular physics. Kinetics of chemical reactions, and collisionalradiative model for spectroscopic diagnostics. |
| Fusion System Engineering |
2 | This lecture is an introduction to fusion engineering. Features and functions of fusion power plant systems and their subsystems such as superconducting magnets, heating devices, divertor, and blankets are reviewed. Concerning the magnets, properties of materials at low temperatures and superconductivity are reviewed, and their issues are discussed. In addition, technical issues of divertor and blankets for high heat flux and neutron irradiation are discussed. |
| Fusion Reactor Materials |
2 | Theories of elasticity, plasticity, strengthening and radiation damage of materials are reviewed. Tensile testing is explained as a major examination for materials, leading to a lesson in evaluation procedures and analyses on the test results. Materials adopted for the ITER, and candidate materials promising for future demonstration (DEMO) reactors are introduced including key properties. Based on the gap between neutron irradiation conditions and operation temperatures in the ITER and DEMO reactors, improvements of properties are discussed with some examples of recent fusion materials development. |
| Fundamentals of Simulation Science |
2 | Learn the basic methods of computer simulation, a powerful tool for investigating complex plasma phenomena. Concepts, basic equations, algorithms, typical simulations performed by practical programs, their visualizations, limitations and numerical errors are described for particle and fluid models commonly used in plasma simulations. |
| Mathematical Physics | 2 | Various methods of mathematical physics are used to treat complex physical systems such as plasmas in which diverse collective phenomena are produced by a huge number of charged particles interacting with each other through electromagnetic force. This lecture presents basic methods of mathematical physics used in analytical and statistical mechanics. As examples of application, one learns plasma kinetic theory, fluid model, and transport theory. |
| Scientific English Writing and Presentation at International Conferences |
2 | Because international collaboration is often required for the successful development of magnetic fusion energy, as seen in the case of ITER, the ability of communication in English is a “prerequisite” to be a successful research scientist. A series of lectures will provide students with the basic knowledge to write and present technical papers in English for international conferences, also with practice in reading technical literature and a with a review of relevant grammatical topics. |

| Exercise of scientific paper analysis |
2 | To write academic papers, it is important to conduct excellent research, but in fact it alone is not enough. “Method of research” differs depending on each theme, but there is a common “method of writing” when summarizing results of research as an academic paper. Rather than merely listing the research results, a story from the intro to the conclusion is necessary. How to make this story will be explained as a “way of writing”. |
| Fusion plasma science seminar |
2 | Learn latest information on research activities by attending colloquiums on fusion plasma sciences. Improve students’ ability of preparing and talking their presentations and learn techniques for making an excellent presentation. Study how to examine their own and others’ researches on fusion plasma sciences by joining the discussions in the colloquiums. |
