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.

The age of fission neutrons to indium-resonance energy has been measured in AGOT graphite using the point-source technique. Corrections to the data arising from the following factors were investigated: (a) source and foil size, (b) finite dimensions of medium, (c) higher- and/or lower-energy activations, and (d) angular sensitivity of detector foils. The age was determined to be 307.8 ± 1.9 cm2; the fourth and sixth moments were 6.58 ± 0.05 × 106 cm4 and 3.84 ± 0.06 × 1010 cm6, respectively. These agree well with the values of 307.4 ± 1.0 cm2, 6.59 ± 0.06 × 106 cm4, and 4.01 ± 0.09 × 1010 cm6 obtained by Monte Carlo calculations.
