Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The first experiments of neutral beam (NB) injection into a field-reversed configuration (FRC) plasma have been performed at FIX (FRC Injection Experiment) device.1 The experimental results show that the configuration lifetime of a FRC have been expanded by about 200% compared with no NB injection case. These results indicate that several hundred kilo watts of NB injection saves several mega watts of global energy losses. For understanding these experimental phenomena, some numerical calculations have been performed. Numerically calculated ionization degree vs. distance along beam injection axis and beam trajectories show that the injected beam ions form dense regions around minimum │B│. These formed hot beam ions walls would play a role in improving these confinements on the edge layer. Some previous theoretical studies pointed out the existence of electrostatic effects in the FRC edge plasma confinements.6, 7 Since only several kilo watts NB injection improves FRC confinement, it seems that the injected hot beam ions encourage electrostatic effects on the edge layer.
