lmpurity lon Diagnostics in the GAMMA 10 Tandem Mirror

We constructed some spectroscopic measurement systems that cover the wavelength range from soft X-ray (SX) to visible lights. We have observed the absolute impurity line intensities, Doppler line broadenings, Doppler shifts by ultraviolet and visible spectrograph and time dependent radial profiles of the impurity lines by the vacuum ultraviolet (VUV) and the SX spectrographs. We determined the radiation loss in the wavelength range from visible to VUV and carbon ion density. These spectroscopic systems could be powerful tools to diagnose the GAMMA 10 plasma in a long pulse operation.
