| Outline of Final Research Achievements |
Development of the next generation neutron target with low radio-activity for medical application is composed of two contents. One is to develop the observation method of proton induced radiation defect. The other is to realize the neutron target to release hydrogen.
Long distance blistering observation system using He-Ne laser light reflection method has developed. Several meters from the neutron target to the observation apparatus is necessary. Special nature of the blistered materials which is a mass of a small mirror on the surface or inside of the surface enables us to construct the shape of the distribution of blisterings. Noble application of the physical vapor deposition technique to the beryllium thin film makes the release of hydrogen gas to outside the neutron target. This process enables the possibility of blistering free neutron target under the irradiation of proton beams.
