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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

We are studying the feasibility of using boron doping to refine the grain structure of sputter-deposited Be for NIF ignition capsule ablators. The goal is to improve the surface finish and homogeneity of these coatings. Films deposited on flat silicon substrates display a pronounced change in structure at a concentration of ∼11 at.% B. At lower levels of B, grain sizes of about 200 nm are observed. AFM images show the roughness of these films to be about 20 nm rms. At higher levels of B, the grains size drops to below 50 nm and the roughness decreases to less than 2.5 nm rms. Films deposited on capsules do not show the same behavior. In particular, at 15 at.% B, the capsule coatings have nodular structure with an rms roughness of greater than 50 nm. When viewed in cross section, however, no structure is seen with either the flat films or the capsule coatings. We believe that differences in substrate temperature may be largely responsible for the observed behavior.
