JAEA-Conf 2011-002 Fig. 7. Deuteron production DDXs for 290 MeV/u oxygen incidence on copper target, together with the PHITS code calculations (solid lines). 5. Conclusion In this study, the DDXs on deuteron production reactions are investigated for oxygen incidence upon carbon, aluminium and copper targets using the GSO(Ce) scintilator spectrometer. As results, the DDXs were obtained in energy region from 100 MeV to 540 MeV at forward angles of 5, 10 and 15 degrees. The measured DDXs were compared with the calculated ones by PHITS code. The simulated results generally agreed with the measured ones but discrepancies were observed in the energy region over 400 MeV at 5 degree. The experimental data will be useful as the benchmark of existing simulation codes and for the future improvements of simulation codes.

We may expect ADS to dramatically reduce the hazard level of the nuclear waste and to operate as the energy generator. To realize ADS, it is necessary to conduct a number of fundamental researches and technical developments in the various areas. Double differential cross section (DDX) data of nucleon-actinide reactions is of the high importance for the nuclear waste transmutation facilitated by the ADS. 1. Introduction In order to obtain high-quality nuclear data of DDX (Double Differential Cross Sections), it is necessary to use a detector that offers the moderate energy resolution of a few percent and a wide energy acceptance covering from almost zero up to the maximum emission energy. Moreover, detection efficiency should be high enough for the usage of a thin target. A crystal array detector is the most suitable one under these conditions and the only solution above 100 MeV. A new crystal array detector has been proposed for conducting the charged particle cross section measurements with the actinide targets for a study of accelerator transmutation of nuclear waste. The detector enables both the Time-of-Flight and the Pulse-Height measurements in an energy range from 10 MeV to 600 MeV. Since the detector is planned to cover secondary particles from protons to 4 He, in the present research we investigated characteristics of BGO crystals in terms of the light output and the peak efficiency for charged particle bombardments. 2.
