    Notes: A system for imaging complete tokamak edge cross sections using radiation from intrinsic low-Z impurities, such as carbon, with a frequency response of 500 kHz and a spatial resolution of 1–4 cm (depending on the thickness of the radiating region) is being developed. The noise level is determined by the electronics and is ≤2% for the full 500 kHz bandwidth and ≤1% for a 100 kHz subset of that bandwidth. Photon noise is 0.3% for the full 500 kHz bandwidth. This diagnostic can be used for studying fluctuations in Prad(λ), Γz, and Te. Additionally it may be useful for studying marfes and detached plasmas, transport and oscillations during pellet injection, and as a fast disruption precursor monitor.

    Study of impurity radiation on the PLT and TFTR tokamaks with high-resolution, time-resolving spectrometers (1985)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Soft-x-ray (5–300 A(ring)) spectra of intrinsic impurities have been recorded with a high-resolution multichannel XUV spectrometer (SOXMOS). Measurements of line intensity ratios as a function of time are applied to the determination of the impurity contribution to the energy balance. Results from TFTR Ohmic heated plasmas, including radiation due to carbon, oxygen, iron, nickel, chromium, titanium, and zirconium, are presented. The spatial ion distribution will be directly observed by a radial scanning spectrometer (FLOPSY). This instrument, under construction, will cover the spectral range from 1500 to 7000 A(ring) and use mirrors and lenses for fast scanning. The spatial ion distribution, deduced from forbidden and allowed lines, will be compared to both theoretical models based on impurity concentrations and transport coefficients, as well as experimental data from bolometer measurements.
