摘要

A novel 2D toroidal plasma flow velocimetry has been developed using tomographic reconstruction technique. The 2D imaging of local ( R-Z ) toroidal velocity is achieved by the vector tomographic reconstruction technique and multi-chord 2D spectroscopy by 35-channel optical fiber array. Numerical simulation for reconstruction of bi-directional toroidal velocity profile suggests that the cost-effective arrangement of the optical fiber for a toroidal plane is 7. We installed the system with 7 × 5 chords arrangement to the TS-4 device. This system successfully measured 2D bi-directional toroidal velocity profile around X point with 10% accuracy during the counter-helicity magnetic reconnection experiment.
