Research fields related to plasma physics have been rapidly expanding in recent years ---from fundamental studies on fusion energy and plasma propulsion to industrial applications using atmospheric plasmas. In the first part of the course, plasma phenomena existing in our surroundings and the universe are briefly reviewed, and then students learn the basics of plasma such as generation methods, characteristics, boundary phenomena, and particle kinetics. In the next step, derivations of the Vlazov equation, fluid equation, and magnetohydrodynamic (MHD) equation from the fundamental equations of plasma kinetic theory are explained. In these processes, students learn the collective behaviors of plasma such as instabilities and waves. In addition, topics on advanced plasma studies are occasionally introduced so that students can learn how plasma physics are utilized to understand practical phenomena.
By the end of this course, students will be able to:
1) explain basic characteristics of plasma
2) explain basic equations governing plasma related phenomena,
3) apply ideas from plasma physics to practical plasma .

|Intercultural skills||Communication skills||✔ Specialist skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
In the beginning of each class, solutions to exercise problems given in the previous class are reviewed. In the end of the class, students are given exercise problems related to the contents of the lecture. Students should check the course schedule and what topics will be covered beforehand, and it is strongly recommended for students to prepare and review those topics.
