Abstract
The new impurity survey spectrometer HR 2000+ is used for registration of the most intense spectral lines in the 654-1085 nm near IR range with spectral resolution 0.23 nm and temporal resolution from 4 ms to discharge duration at the COMPASS tokamak. The procedure of the absolute calibration of the spectrometer is described and technical issues and experimental limitations connected with its operation are discussed here.
The measured spectra are interpreted and results are discussed.
