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.

Radial profiles of plasma density and electron temperature have been measured by a fast-scanning probe (FSP) system with various neutral pressures in the MAP-II and DiPS linear devices for the divertor simulation. The probe system is made of three probe tips, two of which is for a Mach probe consisting of two opposite-directional probes, and one is for an emissive probe installed on the pneumatically driven fast-scanning system with stroke of 30 cm. In MAP-II, density at the center has been varied from 1.5 × 1013 cm-3 to 0.7 × 1013 cm-3 with pressures of 5.5 to 112 mtorr, while that of DiPS varied from 3.5 × 1012 cm-3 to 9 × 1012 cm-3 with pressures of 0.8 to 50 mtorr. Relation of density profile with the working pressure/magnetic field is analyzed by using a simple fluid model. Electron temperature at the center is also measured by the Thomson scattering method and compared with those of FSP, which is varied from 0.6 to 6.5 eV
