Abstract
Physics and engineering designs of Chinese First Quasi-axisymmetric Stellarator (CFQS) have been performed under the collaboration between National Institute for Fusion Science and Southwest Jiaotong University. To obtain high plasma parameter and to study the beam ion confinement in quasi-axisymmetric configuration, the installation of neutral beam (NB) injector is planned with CFQS. The feasibility study of NB injection of CFQS is performed by means of beam deposition calculation code (HFREYA) and the guiding center orbit following code (DELTA5D). The injection angle of 48 degrees is most favorable in terms of the deposition and beam ion confinement.
