Present status of the NIFS-SWJTU joint project NSJP for the CFQS stellarator
Institutskolloquium
- Date: Jan 14, 2022
- Time: 09:00 AM - 10:30 AM (Local Time Germany)
- Speaker: Prof. Dr. Shoichi Okamura
- Shoichi Okamura took his PhD in physics department in Tokyo university, Japan in 1977. He then went to the institute of plasma physics in Nagoya university for the plasma confinement research using the rf wave pondera- motive force in the cusp-mirror device. His next research career was a stellarator experiment (CHS) in the national institute for fusion science in Toki, Japan. He studied MHD stability of high beta plasmas and the transport barrier physics. He was also working for the magnetic configuration optimization of the quasi-axisymmetric stellarator. He is now working in the special program for promoting the international collaborations and the Institutional Research (IR) in the Research Enhancement Strategy Office in NIFS.

The National Institute for Fusion Science (NIFS) in Japan started an international joint project for building a stellarator device in China together with a Chinese university in Chengdu city. The device name is CFQS (Chinese First Quasi-axisymmetric Stellarator) which has an advanced stellarator configuration of the quasi-axisymmetry. The device size is R = 1 m, which is appropriate for the university experiment. However, the magnetic field strength is B = 1 T for the ECH plasma production and the NBI plasma heating, for which we can plan plasma confinement experiments with the medium level of beta. The talk will describe the history of this program with reports of the present status of the device construction. The strategy and the important physics targets of the program will be also explained.
