| Outline of Final Research Achievements |
In this study we developed two kinds of high energy X-ray spectrometer. One is compton scattering X-ray spectrometer with the detective energy region of 0.5~5 MeV. The other is photo nuclear X-ray spectrometer with the detective energy region of 3~30 MeV. After this study we succeeded to develop two detectors as planed, and they were implemented to fast ignition laser fusion experiment. The electron energy spectrum was measured via bremsstrahlung X-ray spectrum by them, and we firstly found the generation of the electrons with the energy above 10 MeV which was origin of the low energy coupling efficiency of the fast ignition. The two x-ray spectrometer gave a great progress on the fast ignition laser fusion science.
