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 phase-shifting diffraction interferometer provides full surface mapping of National Ignition Facility (NIF) ablator capsules for surface finish and isolated defects. To integrate this new instrument into the NIF metrology work flow, the measurement must be both quick and accurate. In this work, we developed automated processing algorithms to streamline a large number of manual steps. This enables the process time to be reduced from 1½ days to 2 h per shell, thus meeting the NIF throughput requirement of 20 capsules/week. We also developed methods to quantitatively report the isolated defects and surface roughness in formats that can be benchmarked against the NIF specifications.
