Description

Spatially resolved measurements of ion temperature are crucial for understanding plasma dynamics. A charge exchange recombination spectroscopy diagnostic system based on a heating neutral beam is installed on the HL-2A tokamak. An optical collection system is designed in accordance with the actual geometry of HL-2A and the CVI 529.2 nm (n=8→7) charge-exchange recombination line. Preliminary measurements show that the CX signals have enough signal-to-noise ratio (SNR). The ion temperature and its profiles are obtained through this system for the first time. (authors)
