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.

Neutron yields of 239Pu-Be(α,n) sources are increasing due to the buildup of 241 Am, an alpha emitter, from the beta decay of 241 Pu. The yields and heat outputs of four sources, in which PuBe13 was formed during fabrication, have been followed for several years. Rates of increase in neutron yields at t = 0 vary from 0.3 to 1.9%/yr for initial 241 Pu contents from 0.10 to 0.70%. For three of these sources the increase in neutron yield follows the radioactive decay of the constituents. For the fourth, the increase in neutron yield is greater than expected. A possible explanation is offered.
