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.

Gibbsian segregation has been observed in trinary alloy Al-Li-Mg. The experiment was carried out by means of secondary ion mass spectroscope (SIMS). The experimental results indicated that the lithium concentration on specimen surface reached approximately 100% in the specimen temperature region of 150 to 300 C. The depth profile of Li showed that there was some broadening resulting from recoil implantation by high energy Ar+ ion bombardment. When the specimen temperature exceeded the temperature range in which the lithium enrichment reached the maximum value, beryllium, impurity element in the alloy, segregated to the surface and competed with lithium. Irradiation-induced segregation for Be was also observed in the experiment.
