Strontium: Supply-and-demand success for the DOE’s Isotope Program
The Department of Energy’s Isotope Program (DOE IP) announced last week that it would end its “active standby” capability for strontium-82 production about two decades after beginning production of the isotope for cardiac diagnostic imaging. The DOE IP is celebrating commercialization of the Sr-82 supply chain as “a success story for both industry and the DOE IP.” Now that the Sr-82 market is commercially viable, the DOE IP and its National Isotope Development Center can “reassign those dedicated radioisotope production capacities to other mission needs”—including Sr-89.

The invention of the first laser and many others after that has led to a large amount of different plasma diagnostics using some aspect of the interaction between light and plasmas. In this paper a short review of these diagnostics is given, where the emphasis will be on Thomson scattering and Laser Induced Fluorescence. Thomson scattering is a very powerful diagnostic which is applied at nearly every magnetic confinement device. When the laser wavelength is much smaller than the plasma Debye length, the scattering spectrum is a reflection of the electron velocity distribution, from which local values for the electron temperature and density can be derived. Laser Induced Fluorescence enables to determine the neutral density of different species in the plasma.
