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 the plug potential (PP) bounce ion is quite essential for effective improvement of axial confinement in the tandem mirror, which is bounced by the confining potential hill. We paid attention to the neutral particles changed from the bounce ions through the charge exchange process and measured simultaneously both energy and emergence angle of the neutral particles by use of a charge exchange neutral particle analyzer for measuring bounce ions located near the inner mirror throat (IMT) of the plug barrier cell. We detected successfully the bounce ions during confining potential formation and assigned the bounce ions to the PP bounce ion and the OMT bounce ion which is bounced near the outer mirror throat (OMT) of the plug/barrier cell. The trajectories of the PP bounce ion were calculated, and it was found that the confinement of the PP bounce ion was sensitive to the radial profile of the confining potential in relation to the radial transport.
