Description
Neutron beams have been utilized not only in the basic science, but also in the various industry sectors such as nuclear power, aerospace, defense industry, and semiconductor industry, over the past decades. Although the needs for the nuclear data using the neutron beam extensively have been increased worldwidely, however, it is still insufficient, in particular for the high energy neutron-induced cross sections due to the lack of the high energy neutron beam facility. A neutron beam facility, so-called Nuclear Data Production System (NDPS), is being constructed, so as to measure the nuclear data by employing Time-of-Flight (ToF) technique at Rare isotope Accelerator complex for ON-line experiment (RAON) in Korea. NDPS is planning to complete the installation in 2023. which will provide both white and mono-energetic neutrons using 49 MeV/nucleon deuteron and 83 MeV/nucleon proton beams with graphite and lithium targets, respectively. Since the ToF technique is employed in NDPS, pulsed beams at least less than 200 kHz repetitions with 1-2 nsec width of micro bunch are required in order to obtain sufficient accuracy of the nuclear data. The current status of NDPS will be presented along with the brief overview of RAON.
