The neutron source based on the high power deuteron accelerator has been considered to be used in application fields such as Long Lived Fission Product (LLFP) nuclear transmutation. For the design of accelerator and neutron source, we measured neutron production double differential cross sections for 200 MeV deuteron incident reactions on targets with wide range of atomic number in the Research Center of Nuclear Physics, Osaka University. In experiments, time-of-flight method with liquid organic scintillator EJ301 was applied to measure neutron energies. As a result, the structure of neutron cross section at forward angle had a broad peak at around 100 MeV. In this presentation, the experimental data including previous data for deuteron incident reaction with energies below 200 MeV will be compared with results calculated by codes, and we will discuss about the dependency of incident energies to neutron productions.
