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 multipurpose 14-MeV neutron source based on the T(d,n)4 He reaction is under construction in Bratislava. Its basic purpose is to produce intense and pulsed beams of 14-Me V neutrons. The intense section of the source is expected to continuously produce 1.2 × 1012 n/s with a 20-mA duoplasmatron ion source, 300-kV/40-mA high-voltage power supply, and a rotating titanium-tritium target for 1100 rpm. Although it is designed for a variety of experiments in low-energy nuclear physics involving in-beam gamma-ray, neutron, and charged-particle spectroscopy, neutron activation measurements as well as neutron irradiation studies are also planned. So far, we have completed the main section of the accelerator itself and part of a low-intensity direct current beamline with a neutron yield to 4 × 1010 n/s. A continuation of this line, with a fast pulsed section capable of generating a compressed 1-ns-wide D+ ion beam at a repetition rate of 5 MHz is under construction. The source components, which are designed to be highly reliable and provide minimum radiation hazard from tritium handling, are discussed together with final source specifications.
