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 alpha channeling effect in tokamaks exploits the higher population of high-energy alpha particles in the tokamak interior compared to that of low-energy alpha particles at the periphery. Because of the population inversion, it is possible to inject waves that diffuse resonant particles along diffusion paths connecting these regions, so that hot alpha particles diffuse to the periphery and cool at the same time. This effect has been suggested as a way of achieving considerably higher performance in tokamak fusion reactors, and similar possibilities might be expected in mirror reactors.
