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 Army Pulse Radiation Facility Reactor is a fast pulse, or burst, reactor generally used to provide a fast neutron environment In response to several test requirements, a number of fast neutron-to-gamma converter shields have been designed, calibrated, and placed into operation to produce a pulsed or steady-state gamma environment of ionizing radiation. The four basic converter configurations are (a) a narrow pulse converter box which has produced a maximum gamma dose rate of 3.8 × 108 rad/sec with a pulse width at half-maximum power of 50 μsec; (b) a wide pulse converter box which has produced 6.7 × 107 rad/sec at 400 μsec; (c) a narrow pulse converter cavity that has produced 7.7 × 108 rad/sec at 50 μsec; and (d) a wide pulse converter cavity that has produced 7.7 × 107 rad/sec at 1 msec. In terms of rads tissue, the gamma-to-neutron dose ratio varies from 0.1 (no converter) to ∼5; while in terms of rads (silicon), the neutron dose is almost 2 orders of magnitude less than the gamma dose.
