Diagnostic complex for temporal and spatial measurements in Tokamak

The diagnostic complex presented includes two stigmatic spectrometers for the visible, close UV and IR region with electronic registration: (1) the high resolution spectrometer: wavelength range 200 - 800 nm; light throughput f/3; dispersion changed in the range 0.15 - 2.5 nm/mm; image intensifier in 5 X 104 times; spectral channel number--512; spatial channel number--8; time resolution 1 - 100 msec; the best spectral resolution--0.01 n; dynamic region 4 X 103; (2) survey spectrometer: full wavelength range 200 - 850 nm (for simultaneous registration: 380 - 850 or 200 - 400 nm); f/N--3; image intensifier in 5 X 10+4) times; time resolution 20 - 1000 msec; spectral resolution--0.2 nm; dynamic region 4 X 103. This complex was used for diagnostic measurements at the TSP and T-11M Tokamak (Russia) and for investigations in the diverter region of DIII-D Tokamak (USA). The results of these measurements are presented.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
