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.

We have successfully fabricated 2 mm beryllium targets pressurized with a gas mixture of ~20 atm deuterium and ~0.1 atm argon. These targets have been used for indirect drive Inertial Confinement Fusion (ICF) experiments on the Z-pinch machine at Sandia National Laboratories leading to record neutron yields of ~3.5 × 1011 [J.E. Bailey, et al., "Be Capsule Implosions Driven by Dynamic Hohlraum X-rays," Bull. Am. Phys. Soc. 51, 107 (2006)]. This paper will discuss the process of fabricating such targets from intact shells (Be sputter coated CH mandrels). These processes include laser drilling a ~6 m diameter fill hole in a shell, removing the CH mandrel by pyrolysis, pressurizing the target with a deuterium/argon gas mixture and sealing the fill hole using UV glue while under pressure. The targets were characterized for gas pressure and deuterium gas permeation half-life by utilizing techniques including mass spectrometry, x-ray fluorescence spectroscopy and controlled shell bursting.
