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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Two screened, thin-foil charge collectors were mounted just beyond the plasma edge at an outboard position (below midplane) in the Joint European Torus to detect lost alpha particles during the 1997 high fusion power D-T experiments. No convincing observations of alpha-particle collection were obtained, possibly because of the low level of alpha-particle losses but more probably because the positioning of the detector was not ideal for the high fusion power discharges that were run at high plasma current and toroidal field. Under such conditions, alpha particles on escaping orbits leading toward the detector are highly likely to be intercepted by the nearby poloidal limiter. Moreover, a small alpha-particle signal would have been obscured by interference from a large and unexpected signal attributed here to fast neutrals, leaving the plasma and ionizing in the low density scrape-off region outside the plasma boundary. The interpretation of this unexpected signal is discussed. In all probability, it will also be encountered in any future attempts to detect lost alpha particles in a current measuring detector unless suitable precautions are taken, e.g., provision of a thin first foil to remove light charged particles with energies below ~0.5 MeV.
