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 coupling of lower hybrid waves from the two multijunction-type antennas installed on Tore Supra is investigated. At low power good agreement between the measurement of the power reflection coefficient and the computation with the ALOHA code is found for most cases. Details on electron density measurements, documented from embedded Langmuir probes, are discussed. At high power, departure from the linear theory is clearly seen in many cases. Ponderomotive forces depleting the electron density in a thin plasma layer in front of the antennas are likely to be responsible for the increase of power reflection coefficients measured at the input of the antennas. The decrease of the antenna directivity resulting from weaker wave coupling accounts for the experimental reduction of current drive efficiency.
