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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

The paper presents experimental data on plasma heating in a new regime of GOL-3 operation. Unlike previous experiments, the new regime features significant growth of energy of electrons in a relativistic electron beam during the beam pulse.The new dynamics of beam energy during the shot changes dynamics of plasma heating. A pronounced feature of previous GOL-3 experiments on plasma heating in the corrugated magnetic field was early transition to the plasma cooling stage, which in some regimes occurred much earlier than the beam injection stopped. In the gradual-energy-growth regime, plasma heating continues for a longer period until the beam power decreases significantly. Some other features will also be discussed.Experiments in the new regime allow us to partially verify feasibility of plasma heating with the electron beam at lowered beam parameters. This is important for the next planned step in GOL-3 program.
