Description

We have been executing forward a research project on the nuclear data. The major part of this project is measurements of the neutron capture cross sections of MAs and LLFPs at J-PARC. We are now installing a neutron nucleus reaction instrument (NNRI) at the beam line 04 (BL04) at J-PARC. We designed the beam line to obtain the optimal condition for the capture cross section measurements. The neutronic characteristics of the beam line such as energy spectra, beam spot shape, and time structure of the emitted neutrons are very important since it decides the performance of the experiments. We measured the neutron beam characteristics of the beam line and found that they were consistent with those we expected. Measurements on the samples of Cm as MA, and Tc-99 and so on as LLFP are now on progress. (author)
