Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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 fine-grained mobile pyrolytic graphite limiter was biased to generate radial electric fields in the plasma edge region of the TJ-II stellarator to improve confinement operation modes. Indeed, for the range of voltages applied (up to ±300 V), spectroscopic data indicate that limiter biasing does not induce significant external influxes of impurities. Also, after boronization of the vacuum chamber, increases of ~100% in electron density, together with reductions of the order of 40% in Zeff, are observed during limiter biasing. Here, we report on the first study of impurity behavior in the TJ-II during externally induced radial electric fields. For this, different spectroscopic methods were employed, and the results obtained were compared to assess impurity behavior and to evaluate the effectiveness of such biasing on plasma confinement in TJ-II.
