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.

College students help develop waste measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Two types of neutral beam sources have been developed in order to measure plasma parameters on the Hanbit mirror device. The first source is a diagnostic neutral beam (DNB) which consists of a hydrogen neutral beam with a beam energy of 30 keV and a total beam current of ca. 1 A. The ion temperature profile can be determined by measuring directly the broadening of the Hα line emitted from hydrogen neutrals produced through the charge exchange recombination reaction with the DNB in the plasma. A fibre optic array detector, which works as an ideal notching filter, was developed to filter out the intense Hα line emitted from the cold hydrogen atoms in the plasma edge. The second source is a hyperthermal neutral beam (HNB) which consists of neutral particles with an energy of 1-100 eV. The HNB can be used to measure electron temperature and density profiles in the region between the core and the outer edge. This region cannot be covered either by Thomson scattering or by electrostatic probes. The feasibility of obtaining profiles of electron density and temperature by means of a helium HNB with a collisonal radiative equilibrium code has been performed.
