Nuclear News 40 Under 40 discuss the future of nuclear
Seven members of the inaugural Nuclear News 40 Under 40 came together on March 4 to discuss the current state of nuclear energy and what the future might hold for science, industry, and the public in terms of nuclear development.
To hear more insights from this talented group of young professionals, watch the “40 Under 40 Roundtable: Perspectives from Nuclear’s Rising Stars” on the ANS website.

Fraction of a neutral beam particle with the different energy has been investigated in the Large Helical Device. We adopt a low-energy (40keV-3MW) neutral beam injection system in order to improve the ion temperature. A visible-spectrometer coupled intensified charge coupled device detector has been installed in order to measure a hydrogen beam emission spectrum inside of a target plasma. The spectral resolution and the reciprocal dispersion are 0.21nm and 1.4nm/mm, respectively. We typically use the 40ms sampling times with the 20ms exposure times. We have clearly observed the beam emission spectra from a hydrogen neutral beam with the energy of full, half and 1/3. We have also estimated the fraction of the full-energy beam component from the beam emission intensity. Total injection beam power is improved by increasing of the fraction of the full-energy beam component.
