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 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. 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.”

Density gradient laser targets with decreasing density or increasing stepwise density layers were reported in experimental and theoretical papers on astrophysics modeling, equation-of-state (EOS), and shock-wave dynamics studies. The research with targets of smooth density gradient is due. The experiments with gel-catalyst concentration diffusion are discussed for density gradient foam formation. We used multi-image X-ray tomography for measurement of the silica gel layer density gradient in the process of its growth. Gel with a density gradient growing from a flat boundary between a gel-forming solution and a catalyst solution has been investigated through a set of three-dimensional frames of an X-ray computer microtomograph. Laser targets require high (>1 gcm-3/cm) density gradients of the spatial profile for EOS experiments. The first targets from silica aerogel with a density gradient are demonstrated. Yet these targets perform less density gradient (<0.1 gcm-3/cm) than is required for pressure multiplication in EOS targets.
