ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Experimental study on tritium retention in tungsten was conducted, in which samples were irradiated with MeV-energy H or He ions and deuterium concentration profiles were subsequently observed under deuterium-plasma exposure conditions. The results showed that the deuterium concentration was significantly increased by irradiation at 573 K due to production of hydrogen traps while it was not under irradiation below 400 K. In the latter case, however, the concentration was increased when the sample was heated around 550 K. The trap was considered to be a kind of interstitial defects and grown at 550 - 600 K from irradiation defects. Once produced, the trap was stable at least 710 K.
