Novel materials are developed with resistance for severe environment based on material design.
1) R&D of ceramic material for advanced energy application
The research activity puts emphases on R&D of the advanced ceramic materials like SiC/SiC composites for nuclear advanced fission, fusion and aerospace application utilizing nano-technique. The R&D include development of novel materials, applications and environmental effects from basic science through engineering. Many collaborative researches are ongoing with domestic and international institutions in US, Italy and OECD.
Development of Particle Dispersion SiC Composites
Interphase between fiber and matrix is the weakest link for conventional SiC composites in terms of environmental effect.
Novel SiC composites with particle dispersion SiC matrix was developed without the interphase. The SiC composites have excellent oxidation and corrosion resistance.
2)Transverse Laser Cooling of a Magnesium Ion Beam by Synchro-Betatron Resonance
As collaboration research with Advanced Research Center for Beam Science, Institute for Chemical Research, Kyoto University, K. Jimbo engages in a laser cooling experiment of a magnesium ion (24Mg+) beam at Small Laser-equipped Storage Ring (S-LSR). As shown in the picture, the wavelength variable UV laser (280 nm) is guided into a straight section of S-LSR and co-propagates with ions so that they constitute 3s2S1/2→3p2P3/2 absorption- emission cycle for laser cooling. Cooling in the longitudinal direction has already been achieved for both coasting and bunched ion beams. Now we try to cool ion beams in the transverse direction by the synchro-betatron resonant coupling.
Small Laser-equipped Storage Ring (S-LSR)
S-LSR located at Advanced Research Center for Beam Science, Institute for Chemical Research, Kyoto University has 6-fold symmetry with circumference 22 m.
