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.

PNNL seeks high-energy neutrons from SpaceX launch of Polaris Dawn
When a SpaceX rocket lifted off from Kennedy Space Center on September 10 (see video here), sending a crewed commercial mission into low Earth orbit, an experiment designed by Pacific Northwest National Laboratory was onboard. Several high-purity metal samples will orbit Earth and absorb cosmic radiation for five days—including that from the Van Allen radiation belt—to help the lab answer questions about the radiation environment for manned space missions, according to a news release from PNNL.

The Spanish Technofusion project includes an irradiation laboratory equipped with two tandem-type accelerators (protons/deuterons and alphas) and a multi-ion cyclotron (heavy ions).A radioprotection issue concerning activation of the irradiated samples is to establish the required "cooling" waiting period for safe handling. Samples of iron, Al2O3, SiO2, and SiC are considered here.In dealing with this task, inventory calculations have been performed using, in addition to cross-section data available in different activation libraries, experimental data for some dominant reactions that have not yet been considered in the generation of the corresponding evaluated activation cross sections. Residual dose rate results, calculated from the radioactive inventory determined using both evaluated data alone and a combination of evaluated and experimental data, are compared and the impact of the results on handling limitations analyzed.Very affordable cooling times are found suitable for the irradiated samples. The calculated cooling times meeting safe handling requirements are expected to have high reliability for the proton beam in Al2O3 and the alpha beam in Fe and relatively high reliability for the proton beam in SiO2 and Fe as well as the alpha beam in Al2O3 and SiO2; only deuteron beam is satisfactory for Al2O3; and finally, for SiC, all cases are unsatisfactory.
