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 chamber wall armor is subject to demanding conditions in inertial fusion energy (IFE) chambers. IFE operation is cyclic in nature, and key issues are (a) chamber evacuation to ensure that after each shot the chamber returns to a quiescent state in preparation for the target injection and the firing of the driver for the subsequent shot and (b) armor lifetime that requires that the armor accommodate the cyclic energy deposition while providing the required lifetime. Armor erosion would impact both of these requirements. Tungsten and carbon are considered as armor for IFE dry-wall chambers based on their high-temperature and high-heat-flux accommodation capabilities. This paper assesses the requirements on armor imposed by the operating conditions in IFE, including energy deposition density, time of deposition, and frequencies; describes their impact on the performance of the candidate armor materials; and discusses the major issues.
