Outline of Final Research Achievements |
Charge-changing cross-sections between NBI hydrogen atomic beams and tungsten ions, which is essential to a modeling of tungsten impurity transports in fusion plasmas, have been measured. Actual measurements have been performed at the Tandem accelerator facility in Japan Atomic Energy Agency using tungsten ion beams upto 184 MeV, which is equivalent to the 1-MeV NBI hydrogen beams in velocity, and atomic hydrogen targets. The experiments have gone behind the original schedule because of an unexpectedly slow delivery of a side-lid of the vacuum chamber, but the plan will be completed in FY2015.
