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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

Inertial confinement fusion capsules must be manufactured with a high degree of azimuthal symmetry to avoid degradation by Rayleigh-Taylor instabilities. Therefore, the azimuthal fluctuations of each capsule must be characterized. We have developed a precision radiography method capable of measuring X-ray optical depth fluctuations to 1 part in 104 with a spatial resolution of 120 m. Achieving the measurement accuracy requires counting many photons.Recent measurements of glow discharge polymer (GDP) capsules show that the high X-ray intensity required to minimize measurement time modifies the GDP shell by increasing the oxygen atomic percent. An equatorial band forms that is more optically dense than the remainder of the capsule. We believe that free radicals are formed in the GDP as a result of the X-ray exposure. These free radicals preferentially absorb oxygen from the air. We will discuss how this optically dense band forms, how it is measured, and possible solutions to this issue.
