Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

Magnetic sail (MagSail) is a next-generation deep space propulsion system, which uses the energy of the solar wind. The MagSail produces an artificial magnetic field and captures the energy of the solar wind plasma to propell a spacecraft in the direction of the solar wind. In order to conduct a scale-model experiment of the plasma flow of a MagSail, we developed a solar wind simulator based on a magnetoplasmadynamic arcjet, which obtained a high density (~1018 m-3) and high velocity (~60 km/s) plasma flow in a quasi-steady mode of about 1 ms duration. Based on scaling considerations, a solenoidal coil (18 mm in diameter and the magnetic flux density at the coil center ~ 1.9 T) was designed and was immersed into the plasma flow. A magnetic cavity, which is very similar to that of the geomagnetic field, was observed, although the magnetic cavity of MagSail is usually much smaller than the geomagnetic cavity of the Earth.
