Outline of Final Research Achievements

The coherent transition radiation (CTR) is generated from the high-energy electron beams of a linear accelerator (linac) and is used as the intense light source in a THz region. The CTR light source established by using an electron linac in Kyoto University Research Reactor Institute was used for the present work. The new system for absorption spectroscopy and irradiation was developed. In the CTR absorption experiments, for the basic materials of living things, water and water solution of NaCl, the possibility of non-linear effect and the dependence of the concentration of NaCl were observed. In the irradiation experiments for bacillus, cell and microorganism any change was not observed, which showed the future direction in the researches.
