ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

The invention of the first laser followed by many others 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 that 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.
