摘要：

The edge tangential Thomson scattering system (ETTSS) was developed for the first time on a HL-2A tokamak. A Nd:YAG laser with a 1064 nm wavelength, 4 J energy, and 30 Hz repetition rate is employed on the ETTSS. The laser beam injects the plasma in the tangential direction on the mid-plane of the machine, and the angles between the laser injection direction and the scattered light collection direction are in the range from 157.5 degrees to 162.8 degrees. The scattered light collection optics with 0.21-0.47 magnification is utilized to collect the scattered light of measurement range from R = 1900 mm to 2100 mm (the normalized radius is from r/a = 0.625 to 1.125). Spatial resolution of the preliminary design could be up to Delta r/a = 0.016. The measurement requirements could be achieved: 10 eV < Te < 1.5 keV, and 0.5 x 10(19) m(-3) < n(e) < 3 x 10(19) m(-3) with errors less than 15% and 10%, respectively. Published by AIP Publishing.
