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.

Concerning an application of a cusp type direct energy converter (CUSPDEC) to high density plasma, subjects on charge separation and deceleration have been experimentally investigated, assuming that previously proposed two-stage deceleration scheme will be employed. As a fundamental measurements on two-stage deceleration scheme, the ions reflected by electric field due to the point cusp ion collector have been successfully detected by a sub-collector as a function of the collector voltage. For efficient charge separation and energy conversion, an introduction of a negatively biased grid has been examined, resulting that the assistance of charge separation to cusp field is effective. By employing the negatively biased grid, direct energy conversion by the point cusp collector also achieved with excluding electrons flowing into the collector.
