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.

Equation-of-state experiments using VISAR require the refractive index of undoped glow discharge polymer (GDP) and Ge-doped GDP at 532-nm-wavelength light. The index was measured with two different techniques. The first technique used measurements of pulsed laser reflections off a GDP foil suspended in refractive index fluid standards. Fluids with different indices were replaced until minimum reflection was achieved; this occurred at the matching index of the fluid and GDP film. The index of the correct matching fluid (or fluid mixture) was measured with an Abbé refractometer to produce nD (the refractive index at sodium D line, 589 nm) and was corrected for wavelength using manufacturer-supplied Cauchy equation coefficients. The second technique used interferometry to measure fringe shift over GDP and Ge-GDP bumps when submerged in various refractive index fluid standards. The fringe shift was minimized when matching the indices of the fluid and film. The refractive indices at 532 nm were 1.563 and 1.570 for undoped GDP and Ge-doped GDP, respectively.
