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.

Thermal conductivity of electroplated gold at cryogenic temperatures is an important parameter for predicting the thermal behavior of ignition hohlraums that will eventually be fielded on the National Ignition Facility. We have measured the ratios between the electrical conductivities at 4.2 K and room temperature for electroplated gold as a function of bath brightener concentration and plating current density. By using the Weidemann-Franz law we predict thermal conductivities of these samples. We find that even small amounts of bath brightener drastically reduce the conductivities, and that the conductivities have a strong dependence on plating current density.
