Hydrogen and deuterium ion species mix and injected neutral beam power fractions of the TEXTOR-PINIs for 20-60 kV determined by Doppler shift spectroscopy
The ion species fractions of the multi-megawatt neutral beam ion sources for TEXTOR were determined by H(alpha)/D(alpha)-light Doppler shift spectroscopy. The ion species mix of the extracted beam was measured for energies in the range 20 - 60 keV and beam currents of 13 - 100 A. The maximum H(+)/D(+) fraction at full power operation is 66 % - 69 %. No significant difference was found between two ion sources (PINI) mounted on the neutral beam injectors.
