The newest era of workforce development at ANS
As most attendees of this year’s ANS Annual Conference left breakfast in the Grand Ballroom of the Chicago Downtown Marriott to sit in on presentations covering everything from career pathways in fusion to recently digitized archival nuclear films, 40 of them made their way to the hotel’s fifth floor to take part in the second offering of Nuclear 101, a newly designed certification course that seeks to give professionals who are in or adjacent to the industry an in-depth understanding of the essentials of nuclear energy and engineering from some of the field’s leading experts.

The design of a new type of neutral beam injector that recovers the energy of the unneutralized part of the beam, developed at Cadarache Laboratory, is presented. The experimental work done since 1987 is also reviewed. In a recent joint Japan Atomic Energy Research Institute (JAERI)/Commissariat à l'Energie Atomique experiment, the injector was operated with extracted deuterium ion beams of up to 85 keV/35 A and 100 keV/14 A by utilizing a plasma generator developed at JAERI that supplies up to a 94% monoatomic ion content. From energy recovery measurements, an improvement in the injector electrical power efficiency by up to 25% for a 100-keV deuterium beam operated with a 6 × 1015 mol/cm2 neutralizer gas target thickness is deduced.
