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.

A new type of divertor, a dipole divertor, is described. The dipole divertor is composed of a line dipole and is characterized by a simple configuration and the realization of a double-null separatrix with a small distortion on the equilibrium magnetic surface shape. Various configurations, including a conventional divertor, can also be realized with the basic two current hoops by changing current direction and magnitude. Higher-order multipole divertors such as the quadrupole divertor are also formed by four or more coils. A divertor magnetic field can be further localized in the higher-order multipoles. A possible stabilizing effect through curvature of the field line is discussed.
