Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

The gamma-ray production cross section of oxygen has been measured at incident neutron energies between 7 and 10.5 MeV. The production of the 6.13-, 6.92-, and 7.12-MeV gamma rays by the (n,n′γ) reaction in 16O and the 3.09-, 3.68-, and 3.85-MeV gamma rays by the (n,αγ) reaction has been studied. In addition, the production cross section of the 4.44-MeV gamma ray from inelastic neutron scattering on carbon has been measured at one neutron energy, since many earlier measurements of gamma-ray production cross sections have been performed relative to this cross section. Monoenergetic neutrons were produced by the 2H(d,n)3He and 3H(p,n)3He reactions. The gamma radiation was detected by a large Nal(Tl) scintillator using time-of-flight techniques. The neutron flux was measured by means of a proton-recoil telescope using the n-p scattering cross section. The differential gamma-ray production cross sections were measured at 90 deg. In addition, the angular distribution for the 6.13-MeV gamma ray was determined at one neutron energy. The results for oxygen, which show pronounced structure of the cross section for the 6.13-MeV gamma ray over the whole energy region, are in disagreement with current data files, whereas the results for carbon are in agreement with a number of recent investigations of the 12C(n,n′γ)12C and 12C(n,n′)12C reactions.
