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.”

Concerning an application of a cusp type direct energy converter (CUSPDEC) to high density plasma, subjects on charge separation and deceleration have been experimentally investigated, assuming that previously proposed two-stage deceleration scheme will be employed. As a fundamental measurements on two-stage deceleration scheme, the ions reflected by electric field due to the point cusp ion collector have been successfully detected by a sub-collector as a function of the collector voltage. For efficient charge separation and energy conversion, an introduction of a negatively biased grid has been examined, resulting that the assistance of charge separation to cusp field is effective. By employing the negatively biased grid, direct energy conversion by the point cusp collector also achieved with excluding electrons flowing into the collector.
