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.

A 106-GHz electron cyclotron heating system is installed and operated for plasma production and heating of the Heliotron-E helical device. The Gaussian beam radiated from the gyrotron is coupled to the HE11 waveguide mode by the matching optics unit (MOU), then transmitted through 15-m corrugated waveguides and four miter bends. The system is closed for safety to prevent spurious modes from radiating into the free space and is operated at atmospheric pressure. The transmitted wave is launched from the outside of the torus, and the launched beam is focused on the magnetic axis so that the power deposition is expected to be localized at the desired resonance region. The measured transmission efficiency from the MOU output to the launcher output is 86%, which is in good agreement with the theoretical estimate. The power losses arise mainly at the waveguide mouth where the Gaussian beam is coupled to the HE11 mode, at the miter bends and in the launching system.
