| Outline of Final Research Achievements |
We carried out impact experiments and measured X-ray radiation. At first, the experiments are done at Osaka University where various X-ray detectors are available and recently new projectile acceleration system has been developed. There are signs that X ray is radiated when projectiles impact, but there are some noises due to high-temperature plasma caused by laser irradiation. Then, we construct new systems where sold samples are destructed by not laser irradiation, but compression using a hydraulic press and impact of hypervelocity projectiles using a two-stage light-gasu gun. We actually observe x-ray radiation when rock samples are disrupted and find that the x-ray counts depend on the size of the samples.
