Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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 objective of the present study is to analyze separation capability of charged particles of small-scale cusp type direct energy experimental converter installed at GAMMA 10 by means of numerical simulation with the axisymmetrical two-dimensional approximation. The numerical simulation has given the following results: (1) when the input power of protons is less than or equal to 1W, the protons and the electrons can be separated with the proton collection efficiency of 100%. When the input power of protons is 5W, the protons and the electrons become difficult to be separated with the proton collection efficiency of about 5%. (2) The electrons whose radius of incidence is small become trapped in the separation zone. These results depend on the magnitude of self-induced electric field which is formed by separation of the protons and the electrons.
