| Outline of Final Research Achievements |
In this research, divertor simulation experiments have been performed by using high heat-flux plasma flow from the end of the large tandem mirror device GAMMA 10 in order to investigate the operation scenario for the divertor which is an essential component for nuclear fusion reactors. A diagnostic tool was installed at the mirror end and the heat flux of more than 10 MW/m^2 has been achieved under a good controllability with the radio frequency power applied to the tandem mirror plasma. By using a divertor simulation experimental module installed at the end-mirror exit, high heat-flux plasma flow injected from the end-mirror was successfully reduced and formation of plasma detachment was clearly confirmed. In order to simulate the intermittent heat flow from the periphery plasma in edge region, a new ion beam injection system was developed and fundamental characteristics on beam convergence under to open magnetic field configuration of GAMMA 10 end-cell have been studied.
