| Outline of Final Research Achievements |
This study intends to propose and verify a new concept of fusion divertor that utilizes energy by extremely large heat transport capability. The divertor device investigated in this research receives high heat and particle flux on tungsten armor covering thin copper target material, followed by heat transport in small temperature gradient as latent heat by heat pipe mechanism, that was fond to be optimum. This feature was found to be subject to the repeated pulses by plasma mode named ELM, and the test was performed with YAG laser to simulate this effect. The heat transport performance was proved to be affected little by this heat pulses, and the concept of this divertor was verified to effectively convert fusion energy from plasma and provide it for the power train for electricity generation.
