Outline of Final Research Achievements

We have developed a heavy ion beam probe (HIBP) in order to measure the electric field and turbulence which determine particle and heat transport in magnetically confined high-temperature plasmas. Several methods to detect high-energy probe ions efficiently have been developed. As the results, we have demonstrated that the signal intensity increases 4 times or more in the case that the high energy probe ions are converted to secondary electrons by use of metal targets.
In plasma experiments, we have identified that zonal flow is driven by high-energy ions in the Large Helical Device (LHD). In addition, we have successfully detected transition of radial electric filed which is predicted by the neoclassical theory, for the first time in the LHD plasmas.
