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 advanced limiter-divertor plasma-facing system (ALPS) has been studied for several years, but the magnetohydrodynamic (MHD) stability of free surface jet flow in a gradient transverse magnetic field is one of the key remaining issues. Recently, some experiments on jet flow were performed with a 0.2- to 1.95-T gradient magnetic field and 2.9, 3.24, and 4.10 m/s velocities for a flow diameter of 6 mm. The results indicated that the transverse gradient magnetic field strongly shortens the jet flow range and the shape of the cross section of the jet flow deforms from round to elliptical and finally becomes a bowed-down shape in the jet flow downstream under these experimental conditions. This paper includes simple modeling of jet flow MHD stability in a gradient transverse magnetic field, which derives the velocity and the area of the cross section of the jet flow along the flow path. The theoretical expected values are in good agreement with experimental results.
