Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

First radially resolved local data on the ion distribution function have been obtained on the Large Helical Device (LHD) from measurements of escaping neutral particle energy spectra by using an impurity pellet ablation cloud as a spatially localized target for the charge exchange with plasma ions. The active diagnostic employs a transversely directed injector of solid pellets and a compact high-resolution neutral particle energy spectrometer capable of observing the ablation cloud throughout the pellet flight across the plasma column. The paper describes the experimental method and presents the initial measurement results. The data analysis is discussed with emphasis on the local ion distribution calculation from the pellet charge-exchange neutral spectra, taking into account the pellet trajectory, the cloud parameters, and the relevant electron capture and stripping cross sections. The estimated carbon/hydrogen ablation cloud neutralization fraction is used for the interpretation of the neutral spectra from tangential neutral beam injection-heated plasmas and from ion cyclotron heating-sustained plasmas.
