It provides profiles of the electron temperature and density in the plasma edge at a repetition rate of up to 200 Hz. | |||
It is located at φ = 85.3º ([[TJ-II:Sectors|sector]] A8). | It is located at φ = 85.3º ([[TJ-II:Sectors|sector]] A8). | ||
The signals are stored in the [[TJ-II:Shot database|TJ-II database]] with the names 'He_xxx_yy', where 'xxx' is the wavelength in nm (667, 706, or 728), while 'yy' is the position (from 01 through 16). | |||
