报告摘要：The Chinese First Quasi-axisymmetric Stellarator (CFQS) is a joint project of international collaboration. It is jointly designed by the Southwest Jiaotong University (SWJTU) in China and the National Institute for Fusion Science (NIFS) in Japan. The target parameters of CFQS are chosen as follows: the toroidal period number Np = 2, major radius R0 =1.0 m and magnetic field strength Bt =1.0 T. Via the scan of major radius, aspect ratio and coil numbers, the target parameters of the CFQS configuration are determined by comprehensively considering physical and engineering constrains on equilibrium, MHD instabilities, neoclassical and turbulent transport, etc. It turns out that the configuration for a 16-coil system with Np =2, R0 =1.0 m, a=0.25 m, Bt =1.0 T and aspect ratio Ap=4.0 is the most preferable. In addition, the engineering design for the modular coils, the vacuum vessel and support structures of the CFQS has also been preliminarily performed.
