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.”

Physical sputtering of Mo bombarded by Ar+, blistering and flaking of Mo implanted by He+ ions are described in the present paper. The sputtering yield of Mo was approximately constant in the energy range of 10–20 Kev while the sputtering yield vs. incident angle rose with increasing incident angle in the experiment. Blistering and flaking was observed in the ion fluence range of 7 × 1017 — 1 × 1019 ions/cm2 but only surface protrusions become important when the ion incident angle was near 60°. It means that the sputtering became the dominant process comparing with blistering in this case. The “trackrace effect” of blistering has been found at room temperature and even inside the ion beam spot.
