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.

Katy Huff reflects on her time in the Office of Nuclear Energy
After three years in the Department of Energy, including two as assistant secretary of the Office of Nuclear Energy, Katy Huff stepped down in May to return to the world of academia as a professor at the University of Illinois–Urbana-Champaign.
Among her many accomplishments while serving as NE-1, Huff pushed for energy security—both at home and abroad, in places like war-torn Ukraine—and for the development of additional advanced and traditional nuclear plants, the potential restart of shuttered nuclear facilities, and a better funding stream for college nuclear programs.

Double-differential neutron yields from 400 MeV/nucleon 56Fe stopping in C, Al, Cu, and Pb targets are reported, along with Particle and Heavy Ion Transport Code System (PHITS) transport model calculations of the data. The yields were measured at 90, 120, and 160 deg in all four systems. Neutron energies were measured from 1 to 2 MeV up to a few hundred mega-electron-volts. The data augment previous measurements made by Kurosawa et al. that were reported for angles between 0 and 90 deg. The measurements for each target were made at two different target orientations, resulting in two different thicknesses of target that neutrons had to traverse before reaching the neutron detectors. The differences in the spectra between two different target orientations are due to neutron transport through the target and as such provide an interesting test of transport model calculations. The data indicate that PHITS reproduces the effects of neutron transport very well but may overestimate neutron production between energies of 10 to 50 MeV in some cases.
