| 英文摘要 | A 0.65 THz Solid-state Source Interferometer-Polarimeter (SSIP) with vertical viewing has been installed for line-integrated density and Faraday rotation measurements on Experimental Advanced Superconducting Tokamak (EAST). The SSIP utilizes three independent solid-state diode sources based on frequency multiplier (X48) to provide the probing beam at a fixed frequency of 0.65 THz with similar to 2.5 mW output power, which provide an Intermediate Frequency (IF) with wide range, and the highest IF is up to similar to 10 MHz. The mixers optimized for high sensitivity, similar to 750 mV/mW, are used in the SSIP system, which permits multichannel interferometer-polarimeter on EAST with a low phase noise. The resolution of the integrated density is 3.3 x 10(17) m(-2), and the Faraday rotation is about 1.5 degrees. The density measurement has been implemented with IF similar to 0.85 MHz, in a plasma with plasma current similar to 300 kA on EAST. The line-averaged density, 3.5 x 10(19) m(-3), measured by the SSIP shows good agreement with the results measured by the POlarimeter-INTerferometer (POINT) system and the CO2 dispersion interferometer system in the same discharge. |
