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.

According to the recent low gas-puff experiments in Hanbit magnetic mirror device, the achievable ion temperature is limited largely by neutral content. For discharges with the low gas-puff with the pre-ionization technique, higher ion temperature is estimated compared to the high gas-puff case. Neutral transport and corresponding particle balance in this low gas-puff discharges in Hanbit are analyzed with the two dimensional Monte-Carlo simulation code coupled with a simple parallel plasma confinement formula. The radial ion temperature and power loss profiles are also derived. The global particle balance is between the plasma pumping and the recycling processes, hence the initially puffed amount of gas has negligible contribution to the total particle source.
