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.

A new helical axis stellarator called Helias-Heliac Hybrid Stellarator(HHHS) is based on the modulated l = 1 helical coil. In order to obtain Helias-like and Heliac-like configurations, toroidal coils, poloidal coils and an additional l = 1 helical coil are adjusted to control magnetic field spectrum. It is shown that the bumpy field with opposite sign to l = 1 helical field is essential to minimize the neoclassical ripple transport. An HHHS configuration with sufficient magnetic well and reduced neoclassical ripple transport is demonstrated.
