| 英文摘要 | A vertical viewing 0.65 THz Solid-state Source Interferometer (SSI) has been installed for line-integrated density measurements on Experimental Advanced Superconducting Tokamak (EAST) . The SSI utilizes two independent solid-state diode sources with 2 mW output power and a base frequency multiplier, which provides a wide range of Intermediate Frequencies (IF) . The high time resolution of 0.1 mu s at a 10 MHz IF has been successfully achieved. The IF signal remains almost constant for several hours without any active frequency stabilization. A sensitivity in the integrated density of 0.77x 10(16) m(-2) has been obtained. The density measurement has been implemented with IF similar to 0.85 MHz, in a plasma with IP = 600 kA and P-LHW = 2.1 MW on EAST . The line-averaged density, 3.5x 10(19) m(-3), measured by the SSI shows good agreement with the results measured by the HCN interferometer system and the POlarimeter-INTerferometer (POINT) system in the same discharge. |
