| Outline of Final Research Achievements |
Boundary plasma has an important role for controlling heat and/or particle load to the plasma facing components of magnetic fusion devices. In this study, precious ion temperature measurements which contribute to understand the boundary plasma property have been done by using probe techniques in a linear steady plasma device and the large tandem mirror plasma device GAMMA 10/PDX. The investigation has revealed the influence of anisotropy of ion temperature in magnetized plasma on the measurement. The new diagnostics system for laser induced fluorescence measurement which is constructed in this study will be adopted to the divertor simulation experiment in GAMMA 10/PDX. Investigation of detached plasma formation for high ion temperature plasma and exploring its control technique have been planned.
