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.

A multimode analysis has been carried out to clarify growing frequencies of a 1-MW, 150-GHz dual electron-beam quasi-optical gyrotron oscillator, with a cavity resonator composed of two coaxial annular mirrors. The results show that the gyrotron can be operated at a single frequency with a fundamental mode in the azimuthal direction for the present range of parameters. Its achievable efficiency is 40% when the magnetic field of the cavity is shifted after the operation mode is grown up.
