Outline of Final Research Achievements |
We investigated the fast laser Thomson scattering system to measure the the electron temperature and electron density profiles of the transient plasma less than milliseconds by the multi-laser system and the burst laser. We succeeded in observing the transient plasma phenomenon at the hydrogen pellet ablation which have less than 1 millisecond by the multi laser system. The time resolution of Thomson scattering measurement was improved from the current 10 ms order to less than 1 ms. For the further improvement of the temporal resolution, a fundamental study of the laser operating in the burst mode was carried out, and laser output of Joule class energy was confirmed. In the future, we will improve the fast-Thomson scattering system higher performance by the conducting international collaborative research, .
