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.

An in situ spectral calibration method for Thomson scattering systems, which uses a double-pass scattering system, has been developed for burning plasma experiments, such as ITER and DEMO. In such machines, space for diagnostics is very limited. For Thomson scattering diagnostics, laser injection equipment and collection optics should be installed in the same port because having multiple ports for a laser and collection optics requires a large amount of space. The design makes the scattering angle wide because the collection optics must be located near the laser entrance. In addition, measurements of high electron temperature (40 keV) are necessary. This paper presents an optimization of wavelength channels for the calibration method, in which two different spectra in the double-pass scattering are considered. Using the optimized wavelength channels achieves good accuracy in electron temperature and relative transmissivities even at wide scattering angles and high Te.
