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 end loss ion energy distributions are measured in Hanbit1 mirror plasma produced by a 3.75-MHz, 500 kW° amplifiers with the slot antenna. The measurement of the ion energy distribution in the end region gives us the important information on the loss cone region of mirror plasmas.
The ion energy analyzer, mounted on the end region of cusp in the Hanbit, is versatile diagnostics designed to measure the parallel ion energy distributions. We can obtain the ion energy distribution from the current-voltage curve by sweeping the voltage on the ion repeller while keeping the other grids properly biased to repel the unwanted species. We show that the end loss ion currents, involved the magnetic confinement, vary according as the strength of magnetic field
We compared an end loss ion distribution obtained from the Hanbit with ion energy from DC discharge to test the analyzer.
