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 new type of divertor, a dipole divertor, is described. The dipole divertor is composed of a line dipole and is characterized by a simple configuration and the realization of a double-null separatrix with a small distortion on the equilibrium magnetic surface shape. Various configurations, including a conventional divertor, can also be realized with the basic two current hoops by changing current direction and magnitude. Higher-order multipole divertors such as the quadrupole divertor are also formed by four or more coils. A divertor magnetic field can be further localized in the higher-order multipoles. A possible stabilizing effect through curvature of the field line is discussed.
