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.

Existence of non-axisymmetric electrostatic potential in the plug region of GAMMA10 yields radial losses of ions in thermal barrier cell. Detailed behavior of ions in non-axisymmetric potential and its contribution to the transport in GAMMA10 is not investigated in details. In this study, by modeling the plug potential and the actual magnetic field in the end-mirror cell and estimating the amount of radial shifts of ions by following ion drift motion per bounce, the resultant mapping equation is used to analyze the orbits and diffusion of ions. Especially, the stability of orbits about the first and second order fixed points is studied and the diffusion due to chaotic orbits is estimated.
