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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Dynamics of a fast-flowing plasma through a magnetic mirror field was investigated. A highly-ionized, high-density, He plasma produced by a quasi-steady MPD arcjet (MPDA) was injected into a magnetic mirror. In a uniform magnetic field region, ion acoustic Mach number (Mi) was almost unity, while in a diverging field region the Mach number increased up to 2-3. When the supersonic plasma flows into a converging field region, a shock-like structure was formed. The subsonic flow downstream of the shock was re-accelerated up to Mi of 2-3. The sonic condition (Mi=1) is satisfied at the magnetic mirror throat as in a conventional Laval nozzle. The adiabatic exponent of ions was evaluated by comparing measured spatial profiles with the prediction from 1D isentropic model.
