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.

The alpha-particle emission spectrum in beam-injected deuterium-tritium (DT) plasma is examined by solving the Boltzmann-Fokker-Planck (BFP) equations for deuteron, triton and alpha-particle simultaneously. It is shown that owing to the existence of energetic component in fuel-ion energy distribution functions due to neutral-beam injection (NBI) and/or nuclear elastic scattering (NES), the fraction of the energetic (> 3.52MeV) alpha-particle generation rate increases significantly compared with the case for Gaussian distribution. Aiming at an application to plasma diagnostics, correlation between the modification of the emission spectrum and the gamma()-ray generation rate from 9Be(,n)12C reaction is studied.
