Comparison between Rutherford scattering and neutral particle analysis in ohmic discharges in TEXTOR
The diagnostic methods for the determination of the ion temperature in thermonuclear plasmas need further development to reach the same standard as that available for electron parameter measurements. One technique to improve this situation is the Rutherford scattering diagnostic (RUSC), which has been installed recently at TEXTOR. To evaluate the potential of this method, the ion temperatures in ohmic discharges are compared with the results obtained from passive neutral particle analysis (NPA), which is usually applied as a standard diagnostic for medium sized tokamaks. The results from both independent methods show good agreement for a range of densities from 1.0 to 4.0 x 1.0 E13/cm3 in deuterium plasmas.
