Abstract

The Rutherford scattering diagnostic at TEXTOR was used to determine the central toroidal rotation speed of the hydrogenic bulk ions in the plasma. During neutral beam injection speeds of the order of 10(5) ms-1 were found. With balanced injection no rotation was observed. A first comparison with charge exchange recombination spectroscopy showed, within the accuracy of the methods, no difference in the derived speeds, in agreement with neoclassical theory. The momentum confinement time of the central hydrogenic ions was found to decrease with the neutral beam power as approximately 1/square-root P(NBI).
