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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

In solving photon transport problems by the Monte Carlo method, parallel-type computers are not well suited to the use of the customary rejection technique for selecting photon wavelength upon scattering. Two techniques of determined length and therefore greater suitability have been studied, with particular application to a machine having 64 processing elements, such as ILLIAC IV. The method involving solutions by Newton’s method of the exact equation derived from the Klein-Nishina formula is found to be still more time-consuming than the rejection technique on both sequential and parallel computers. However, newly devised approximation formulas, corrected by weight adjustment factors, have been found to be much quicker on a parallel computer than the rejection technique, and even competitive on a sequential computer.
