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.

Interaction between shear flows and plasma instabilities in axially symmetric mirrors can lead to improved confinement, observed both in experiments on the gas dynamic trap and in simulations. Shear flows, driven via biased end plates and limiters, in combination with finite-larmor-radius effects are shown to be efficient in confining high-beta plasmas even with a magnetic hill on axis. Interpretation of observed effects such as vortex confinement, i.e., confinement of the plasma core in the dead-flow zone of the driven vortex, is shown to agree well with simulations. Theoretical scaling laws predict such a confinement scheme to be useful even in fusion plasmas.
