Courses specializing in nuclear fusion
| Course(Credits) | Lecturers | |
|---|---|---|
| Fusion Science Special Lecture Ⅰ(1), Ⅱ(1) | Foreign visitors | Topics related to plasma and nuclear fusion will be taken up, and special lectures will be given covering everything from the academic foundations to cutting-edge research. The schedule will be announced at the beginning of each semester. This lecture will be given in English by foreign visiting professors or faculty members of the university. |
| Interdisciplinary Fusion Science (2) | Ejiri and other staffs | In order to realize fusion energy, it is necessary not only to obtain knowledge from various academic disciplines, but also to develop various technologies. On the other hand, the knowledge and technologies obtained through fusion research and development can be applied and applied to various fields, and this interdisciplinary nature is a characteristic of fusion. In this lesson, various aspects of fusion will be introduced, as well as its expansion into various fields. |
| Nuclear fusion practical exercise (2) | All program staff | Practical exercises related to nuclear fusion and plasma are conducted through experiments and theoretical/numerical calculations in three laboratories belonging to the Nuclear Fusion Research Education Program. The contents of the exercises will be explained in the first guidance. Exercise schedules will be coordinated individually between each laboratory's supervisor and the participants. |
| Nuclear fusion energy engineering (2) | Yamada | Nuclear fusion reactors, which aim to generate power using nuclear fusion energy, require engineering technology capable of maintaining a stable burning plasma of over 100 million degrees. This course summarizes the basics of engineering related to fusion energy, and the current status and prospects of engineering research for a DEMO reactor for the purpose of power generation demonstration. The aim of this course is to provide a broad picture of research and engineering regarding fusion reactors operating with ultra-high temperature fusion plasmas. |
| Advanced plasma science and engineering (2) | Inomoto | The construction of ITER, an experimental fusion reactor, has started under international cooperation, and nuclear fusion research is entering a new phase. The purpose of this lecture is to explain and discuss advanced aspects of the physics of magnetically confined fusion plasmas, and their relationship with cutting-edge research. During this course plasma phenomena at the basis of the current issues in the tokamak system for ITER will be taken up, and the related physics as well as the current state of research will be explained in detail. |
| Nonlinear Science (2) | Yamada,Saitoh,Sugama,Tanabe | The keyword "nonlinear" is used in various fields of natural science, social science, and engineering. Phenomena that cannot be represented by linear models have been freed from the negative perception of "deviations from linearity," and are now attracting attention as key ingredients of physical phenomena. In this lecture, we discuss the process of modeling nonlinear phenomena and present methods to analyze the derived models using relatively simple examples. The general theoretical framework of nonlinear science is also explained. |
| Applied plasma engineering (2) | Ono Yasushi,Ono Ryo,Usami,Tanabe | After reviewing basic aspects of plasma physics, we will introduce various plasma application technologies from high to low temperature, and from low to high pressure. The basics of plasma generation as well as the latest applied technologies will also be discussed. |
| Plasma nuclear fusion science (2) | Yamada,Kobayashi | Nuclear fusion is being researched all over the world as an almost inexhaustible energy source for the future. In order to realize a nuclear fusion reactor, it is necessary to clarify unsolved problems in plasma science and engineering, and further research is required. In this lecture, theoretical and experimental approaches to various problems are explained in detail, focusing on the magnetic confinement of high-temperature plasmas. Measurements of plasma parameters and innovative fusion devices other than the magnetic confinement type are also discussed. |
| Fundamental plasma theory (2) | Saitoh,Sugama,Nishiura | Plasma is the fourth state of matter following solid, liquid, and gas, and will be applied to new science and technology in the 21st century, such as nuclear fusion energy and ultra-fine processing of semiconductors. Plasma physics as a science is the key to clarify physical phenomena in space, celestial bodies, and the upper layers of the earth. In plasma, groups of electrons and atomic nuclei (or ions) move in a complex manner, creating various structures. The purpose of this lecture is to teach students the basics of plasma physics by explaining what plasma is, how it behaves, and how it is applied. |
| Plasma measurements methods (2) | Ono Yasushi,Ono Ryo,Usami,Tanabe | This course teaches how to measure various parameters that characterize plasmas, such as electron density, electron temperature, ion density, neutral particle density, and gas temperature. |
| Plasma wave physics (2) | Tsujii | Plasma wave physics is a theoretical framework to describe small perturbations of a plasma. Collisionless high temperature plasmas show many interesting phenomena such as collisionless damping of waves due to the non-local plasma response. In this lecture, we learn from basic wave physics to wave-particle interactions in a non-uniform plasma with emphasis on control of fusion plasmas with waves. |
| Introduction to plasma physics | Shinohara | Learn basic ideas of plasma physics, which can help your startup of nuclear fusion research. |
| Turbulence-induced Transport | Ejiri | After reviewing fluid dynamics and Brownian motion, this course discusses the phenomenon of turbulence (mainly homogeneous isotropic turbulence). Turbulence describes a state in which fluctuations of various scales characterize the entire system, while transport refers to the movement of heat, matter and momentum. In static transport, a macroscopic static gradient exists, and transport occurs proportional to the gradient, but in turbulent transport, fluid motion is characterized by various scales, and the turbulent state cannot be described in such simple way. |
| Edge plasma science and technology | Kajita | In order to realize nuclear fusion, it is necessary to control high-temperature plasmas of 100 million degrees Celsius in a fusion reactor. Controlling edge plasmas between the high-temperature plasma and the reactor wall and understanding the plasma-material interaction are important issues for the realization. In this lecture, I will show in detail the fundamentals of plasma, atomic and molecular processes (ionization, excitation, recombination, etc.) in edge plasmas, divertor, and plasma-material interaction in order to understand the phenomena related to the edge plasmas. Plasma-material interactions will be covered, especially the basics of sheath, particle interactions, sputtering, and arcing phenomena. Measurement methods for characterization of boundary plasmas and materials will also be introduced. |
