摘要: A novel fast-ion D-alpha (FIDA) diagnostic that is based on charge exchange spectroscopy has been installed at ASDEX Upgrade. The uses a newly developed high-photon-throughput spectrometer together with low-noise EM-CCD camera allow measurements 2 ms exposure time. Absolute intensities are obtained by calibrating the system an integrating sphere and wavelength dependence determined to high accuracy using neon lamp. Additional perturbative contributions spectra, such as D2-molecular lines, Stark broadened edge emission, passive FIDA radiation have identified can be subtracted or avoided experimentally. from fast deuterium ions after reactions therefore analyzed continuously without superimposed line emissions large Doppler shifts. Radial information radially distributed lines of sight. investigation velocity distribution possible due t...
