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.

Measurements of the double-differential thick-target neutron yield are made for 75- and 120-MeV 12C5+, 153-MeV 16O5+, and 40-MeV alpha particles bombarding carbon, aluminum, copper, and lead targets. The measured data are parameterized by using the two-component moving source model. The systematic variation of the equilibrium neutron (EN) yield with incident ions and targets is analyzed by using the thus-obtained moving source parameters, and a simple expression is proposed to describe the systematics in the EN yield. The systematic change in the nonequilibrium neutron (NEN) yield was formulated to a simple expression by using the local hot spot model. The proposed expression reproduced well the measured EN and NEN yields.
