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 CHIANTI spectral code consists of two parts: an atomic database and a suite of computer programs, written in both the Python and IDL languages. Together, they allow the calculation of the optically thin spectrum of astrophysical objects and application of spectroscopic plasma diagnostics to astrophysical spectra. The database includes atomic energy levels; wavelengths; radiative transition probabilities; collision excitation rate coefficients; ionization and recombination rate coefficients; and data to calculate free-free, free-bound, and two-photon continuum emission. All data and programs are freely available at http://www.chiantidatabase.org and in SolarSoft, while the Python interface to CHIANTI can be found at http://chiantipy.sourceforge.net.
