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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

The first systematic study of the modulation process of traveling wave direct energy converter (TWDEC), an efficient energy recovery device for fast protons created in an advanced fusion, has been presented. The necessary conditions required for a practical TWDEC modulator were examined. The experimental investigation of modulation characteristics for half-wavelength and one-wavelength modulators was performed. In the one-wavelength modulator, the same effect as the half-wavelength modulator can be obtained by half modulation voltages of electrodes. The modulation effect is sensitive with the phase difference between two RF voltages of the one-wavelength modulator, which could be used for control of modulation effect with a fixed electrode structure.
