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.

Fast waves launched from folded waveguides are proposed as the reference current drive scenario for the ARIES-I tokamak reactor. An RF power of 100 MW at 141 MHz is launched from above the plasma midplane on the outboard side to drive the required 3.3 MA seed current in the core. The entire coupler system is compact, consisting of two poloidally stacked 12-waveguide toroidal arrays with a directivity of >95% and a coupling efficiency of ∼97%. Recent waveguide experiments on RFTF confirmed the high power capability (∼40 MW/m2), and the better coupling and spectrum shaping properties than those of loops. A definitive demonstration experiment on a tokamak is needed.
