Abstract

The 6 MeV HIBP has been installed in LHD. Some components have been developed for using the MeV-range beam. As the results of the development, the secondary beam is detected and the change in the beam energy is analyzed successfully. The plasma potential in the NBI plasma is measured. The measured potential is consistent with Er measured by the CXS, qualitatively. Some issues remain. The trajectory calculation does not agree with the experimental results. And the secondary beam signal shows the strange behavior of the probing beam during ECH. Breaking through the issues is crucial for accurate and flexible measurement.
