Abstract :
A 2 mm microwave interferometer is developed to measure plasma electron density for the J-TEXT tokamak. The interferometer views the plasma vertically through a set of large diagnostic ports and the system is configured as a frequency-modulated interferometer. The interferometer routinely provides real-time feedback control for the gas injection system.
