  • For more than 30 years, the Oak Ridge National Laboratory (ORNL) has performed research and development to provide accurate nuclear cross-section data in the resonance region. Overall, the Nuclear Data (ND) Program is tightly coupled with nuclear fuel cycle analyses and radiation transport methods development efforts at ORNL. As a result, resonance region measurements and evaluations are performed in concert with nuclear science and technology needs and requirements. At the heart of the ND program is the Oak Ridge Electron Linear Accelerator (ORELA) that is used to perform high-resolution neutron cross-section measurements in the resonance region. Recently, an accelerator refurbishmentmore » effort has been initiated at ORELA to improve operation reliability. As a result, new cross-section measurements have been performed at ORELA, and ORELA is readily available to address current and future nuclear data needs in the resonance region.« less
  • Nuclear science activities at the Los Alamos Neutron Science Center (LANSCE) encompass measurements spanning the neutron energy range from thermal to 600 MeV. The neutron sources use spallation of the LANSCE 800 MeV pulsed proton beam with the time-of-flight technique to measure properties of neutron-induced reactions as a function of energy over this large energy range. Current experiments are conducted at the Lujan Center moderated neutron source, the unmoderated WNR target, and with a lead-slowing-down spectrometer. Instruments in use include the DANCE array of BaF{sub 2} scintillators for neutron capture studies, the FIGARO array of liquid scintillator neutron detectors, themore » GEANIE array of high-resolution HPGe x-ray and gamma-ray detectors, and a number of fission chambers, and other detectors. The LANL capabilities for production and handling of radioactive materials coupled with the neutron sources and detectors at LANSCE are enabling new and challenging measurements for a variety of applications including nuclear energy and nuclear astrophysics. An overview of recent research and examples of results is presented.« less
  • The Los Alamos Neutron Science Center (LANSCE) facilities for Nuclear Science consist of a high-energy "white" neutron source (Target 4) with 6 flight paths, three low-energy nuclear science flight paths at the Lujan Center, and a proton reaction area. The neutron beams produced at the Target 4 complement those produced at the Lujan Center because they are of much higher energy and have shorter pulse widths. The neutron sources are driven by the 800-MeV proton beam of the LANSCE linear accelerator. With these facilities, LANSCE is able to deliver neutrons with energies ranging from a milli-electron volt to several hundredsmore » of MeV, as well as proton beams with a wide range of energy, time and intensity characteristics. The facilities, instruments and research programs are described briefly.« less
