Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

The structure of deposited carbon layers formed under various conditions ranging from small scale laboratory to large scale magnetic confinement devices was characterized using Raman spectroscopy. By comparing ion beam and TEXTOR experiments, the deposition temperature is found to be the dominant factor in three dimensional disorder of sp2 sites and sp3 ratio at T>493 K. While, no clear temperature dependence on properties of aromatic rings was observed, indicating other parameters responsible for the aromatic rings present in carbon deposition layers. The carbon layers from JET differed significantly, indicating influence of Be compound formation on Raman parameters.
