The immersion tests of pure titanium were carried out in aqueous solution containing carbonate/bicarbonate with 50 mM-chloride ion under gamma irradiation. The effect of pH on general corrosion rate of titanium were studied. The experimental results showed that the concentration of hydrogen preoxide was increased with pH, and the corrosion rate increased with the hydrogen preoxide concentration. The corrosion rate in pH12 and 13 were 5 to10 times larger than those under unirradiated conditions.

We developed an apparatus for electron irradiation and in-situ current-voltage (I-V) characteristics measurements for space solar cells. The apparatus was interfaced to an electron linear accelerator at Radiation Research Center of Osaka Prefecture University. By using this apparatus, the electron irradiation with the energies from 6 MeV to 12 MeV can be performed at various temperatures from -196 
C to 100 C. In-situ I-V characteristic measurements are also possible at the temperature from -196 C to 100 C. As a first demonstration using this apparatus, we performed two experiments. First, I-V characteristics of a Si solar cell were measured at room temperature and at low temperature. Secondly, the Si solar cell was irradiated with 10 MeV electrons and I-V characteristics were measured at room temperature. The experimental result was compared with those for 1 MeV electron irradiation and 10 MeV proton irradiation.

N) were used. The previous values widely used as intensity standards agreed with those obtained in this study within 4-5% in the 2-11 MeV region, however, showed a monotonous decrease with the increase of -ray energy.

U at the JAEA-Tokai tandem accelerator facility, and separated from the reaction products using an on-line isotope separator. The deduced mass excesses and two-neutron separation energies were compared with those of atomic mass evaluations and theoretical predictions.

Times Cited Count：4 Percentile：36.92(Instruments & Instrumentation)Supersaturated Fe-1.2wt.%Cu alloys were irradiated with 200-MeV Xe and 200-MeV Au ions at elevated temperatures. To make an irradiated region and an unirradiated region in a specimen, a masking plate was put on the specimen during the irradiation. After the irradiation, the hardness was measured by using a conventional microhardness tester or a nano-indenter. We have found that the hardness only in irradiated region increases by the irradiation. The boundary of irradiated and unirradiated regions can be clearly identified by the difference in hardness. The present result implies that swift heavy ion irradiation can be used for the local modification of hardness in supersaturated alloys.
