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.

Low-frequency fluctuations related with a radial electric field are investigated in a magnetized plasma column produced by the electron cyclotron resonance. Various radial profiles of space potential are formed by biasing a segmented endplate. Radial electric field and its shear are obtained by fitting the 6th order polynomials to the potential profiles measured. Two types of fluctuations are observed in this experiment. The flute mode fluctuations which are strongly excited in a range of large electric-field shear are considered to be a Kelvin-Helmholtz instability. The drift-wave mode is stabilized with an increase in the radial electric field regardless of its sign, which also tends to be stabilized by the E×B drift velocity shear.
