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 two plasma sources using a concentrically three-segmented plasma emitter are developed, with which the parallel and perpendicular flow shears can be controlled, respectively. Here the drift-like and Kelvin-Helmholtz instabilities are observed to be excited and suppressed depending on the parallel and perpendicular flow shears, respectively. On the other hand, propagation and absorption of right-hand (R) and left-hand (L) circularly polarized waves, which are related to plasma heating, are investigated under magnetic-mirror configurations. Not only R wave but also L wave is absorbed in the electron cyclotron resonance (ECR) region in the same way, which is considered to be caused by the polarization reversal from the L wave to the R wave. It is actually observed that the L wave is converted into the R wave near the ECR point depending on the electron temperature.
