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.

Smooth and uniform solid deuterium-tritium (DT) layers inside a spherical shell are needed in order to achieve ignition on the Laser Mégajoule (LMJ) facility. The thermal environment around the capsule is the key to meeting the DT layer requirements. While keeping high mode roughness within the specifications at the shot temperature is now guaranteed by a rapid cooling technique, low mode roughness ("shape" of the layer) is still a complicated and demanding subject. A perfectly uniform temperature field around the capsule is needed. Final results of the constant thermal perturbation effects on the layer can be calculated, but the dynamic of reaction is not known. This paper presents a model that allows calculation of the low mode layer behavior depending on a change in the temperature field. This comes down to calculating a target lifetime for the low modes during a thermal transient state.
