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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

In this research, thermal desorption characteristics of deuterium retained at trap sites of W created by irradiation of 300 keV hydrogen ions have been studied. With 10 hours of annealing, about 85% of deuterium was desorbed at temperatures of 300 °C and 350 °C, while deuterium desorption at 250 °C was about 60%. To estimate trapping energy of trap sites in this damaged W, TMAP simulation was performed. The result shows that the trapping energy of 1.29eV well accounted for the result of 250 °C annealing. In view that in the literature the vacancy trapping energy of hydrogen in tungsten was estimated to be close to 1.43 eV and the sensitivity analysis has given an uncertainty for the trapping energy of the order of 0.1 eV, it appears that the dominant trapping site type in the investigated damaged tungsten consists of vacancies.
