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.

Plasma simulation models that use particles and that have been developed for studying the microscopic behavior of a confined plasma in a magnetic field are described. The first model is developed to investigate the anomalous diffusion of particles and energy due to low-frequency electrostatic microinstabilities in cylindrical and toroidal systems. The model makes use of the combination of eigenfunction expansion in one direction and the multipole expansion on a two-dimensional spatial grid for solving Maxwell's equations and for pushing particles. The second model is developed to study the neutral-beam injection heating of a tokamak plasma, taking into account the spatial variation of plasma parameters and the finite ion-beam banana orbit. The self-consistent electric and magnetic fields are totally ignored in this model, and the Fokker-Planck collisions on the beam ions due to background ions and electrons are built in through the Monte Carlo method.
