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 L–mode scaling law of global energy confinement time in ion cyclotron resonance heating (ICRH) is proposed in this paper. The scaling is based on 292 observations from tokamaks PLT, JET, ASDEX, TEXTOR, JFT–2M and JIPP T–IIU. The regression analysis reveals the scaling being of the form: τE α a-0·18 R1·27 IP0·98 BT0·10 K0·20 n̄e0·12 Ptot-0·51. Comparision with other scaling laws and fitting the scaling law to the theoretical constraint model have shown many physical phenomena of ICRH wave damping mechanism. To reach the ignition condition, some modifications of experimental technique and tokamak configuration are needed to enhance the energy confinement time.
