Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

After the attainment of the density doubling due to the potential confinement in 1998, GAMMA 10 experiments have been directed to realization of a high density plasma with potential confinement and also to study dependencies between plasma parameters. These studies are important for understanding of the physics of potential formation in tandem mirrors and also for the development of a tandem mirror reactor. GAMMA 10 experiments have advanced after the last OS2000 Conference where we reported high density plasma production by using an ion cyclotron range of frequency (ICRF) heating at high harmonic frequency and a neutral beam injection in the anchor cell. However, the diamagnetic signal of the high density plasma decreased with application of ECRH. Recently a high density plasma was attained without degradation of the diamagnetic signal, which was attained by adjusting the spacing of the conducting plates installed in the anchor transition regions. Dependencies of particle and energy confinement times and plasma confining potential on the density up to a density of 4×1012 cm−3 are studied for the first time in the high density region.
