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.

General Atomics tests fuel as space nuclear propulsion R&D powers on
General Atomics Electromagnetic Systems (GA-EMS) has announced that it has subjected nuclear thermal propulsion (NTP) fuel samples to several “high-impact” tests at NASA’s Marshall Space Flight Center (MSFC) in Huntsville, Ala. That news comes as NASA, the Department of Defense, the Department of Energy, and multiple nuclear and space technology companies continue to build on recent progress in nuclear thermal rocket design and demonstration.

Based on the experimental data of the total, nonelastic-scattering, and elastic-scattering cross sections and the elastic-scattering angular distribution of 209Bi, a set of optimal neutron optical potential parameters is obtained, and all cross sections of the neutron-induced reaction, angular distribution, energy spectra, gamma-ray production cross sections, and gamma-ray production energy spectra, especially the double-differential cross section for neutron, proton, deuteron, triton, and alpha-particle emission, are calculated and analyzed for n + 209Bi at incident neutron energies <20 MeV. Theoretical calculated data are compared with existing experimental data and other evaluated data from ENDF/B6 and JENDL-3.
