Abstract:The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.
2012) Neutron-capture cross-sections of 244 Cm and 246 Cm measured with an array of large germanium detectors in the ANNRI at The neutron neutron-capture cross cross-sections of 244 Cm and 246 Cm were measured by the time-offlight method in the energy range of 1-300 300 eV with an array of large germanium detectors in the Accurate Neutron-Nucleus Reaction measurement InstrumentANNRI at Material and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research ComplexJ-PARC/MLF. The 244Cm resonances at around 7.7 and 16.8 8 eV and the 246 Cm resonances at around 4.3 and 15.3 3 eV were observed in the capture reactions for the first time. The uncertainties of the obtained cross crosssections are 5.8% at the top of the first resonance of 244 Cm and 6.6% at that of 246 Cm. The rResonance analyses were performed for low-energy ones using the code SAMMY. The prompt g-ray spectra of 244 Cm and 246 Cm were also obtained. Eight and five new prompt g-ray emissions were observed in the 244 Cm(n, g) and 246 Cm(n, g) reactions, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
