NEUTRON FLUX MEASUREMENTS AT THE WENDELSTEIN VII-A STELLARATOR
In addition to charge exchange analysis (CX) and charge exchange recombination spectroscopy (CXRS), the time evolution of the central ion temperature during neutral beam heated plasma discharges in the Wendelstein VII-A stellarator is derived from the neutron flux from thermal D-D reactions. In general, good quantitative agreement between the different methods is obtained. Neutron flux measurements also permit to investigate the slowing down of fast DRU+ ions from neutral beam injection (NBI). The results agree well with the predictions based on the assumption of a collisional slowing down mechanism.
