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.”

New applications of space tethers (High-Voltage Tethered Satellite System project) are discussed in relation with idea1 of an active experiment in the Earth's radiation belts. Two conducting strings are supposed to be tethered between the main satellite and two small subsatellites flying through the ERB. A large potential difference ∼1MV is applied between the tethers by means of a generator carried on the main satellite. The tethers effectively scatter the high energy particles into loss cone of magnetic trap, providing a control of particle life time in ERB. The rigorous theory of the sheath layer formed by relatively cold plasma is developed, yielding the electric field profile, which is then used for the treatment of scattering problem. With the help of Fokker-Planck equation the average rate of particle losses, normalized per 1 km of the tether's length is found to be: (2.5 ÷ 14) · 1016 s−1 km−1 for electron belts and 1.8·1014÷2.5·1020 s−1 km−1 for proton belts. New active experiments in space become possible under the joint realization of HVTSS and HAARP projects.
