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 total neutron cross sections of sodium and potassium have been measured for neutron energies from 0.9 Mev to 1.7 Mev at intervals of 5 kev, with an energy resolution of about 5 kev. Total cross sections of sodium, potassium, and calcium have been measured at intervals of 50 kev from 1.25 Mev to 2.1 Mev, using an energy resolution of about 65 to 75 kev. A neutron time-of-flight method was used in both sets of measurements.
