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 sputtering of beryllium (Be) has been used at LLNL for nearly 30 years in the fabrication of laser targets. Several years ago the prospect of using sputtering to fabricate spherical Be capsules for National Ignition Facility (NIF) targets began to be explored and a basic strategy was developed that involved sputtering down onto plastic mandrels bouncing in a pan. While this appears to be very straightforward in principle, in practice sputtering has been used almost exclusively to make thin films (< 1 micron) on flat substrates. Thick films pose a significant challenge for sputtering while materials on spherical substrates are essentially unexplored. More recently, based on computational results, the point design for the first NIF ignition target capsule was specified as a Be capsule with Cu-doped layers of specific thickness, each layer with a different concentration of copper. While the work described here was motivated by the need to make these layered capsules, progress has been made in developing a more complete metallurgical understanding of the materials that are fabricated and the relationship between the sputter processing and microstructure of these spherical samples.
