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.

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.

Krypton-fluoride lasers have been shown to be promising candidates for inertial confinement fusion (ICF) drivers. These lasers can be effectively pumped with electrical discharges or energetic electron beams (e beams). With discharge pumping, the laser aperture is limited in size to a few centimetres (at atmospheric pressure) because of discharge instabilities that cause a homogeneous discharge to degenerate into arcs. Much larger aperture lasers can be pumped using relativistic e beams. At Los Alamos National Laboratory (LANL), we are constructing high-energy e-beam-driven KrF lasers with apertures as large as 1 m2 for the ICF program. In designing and building these lasers, a number of physics and engineering issues related to large area electron guns (e guns) must be addressed. Among these issues are the following: generation of the relativistic e beams, transport of the e beams into the laser gas, and design and construction of pulsed power devices for driving the e guns. Cold cathode e guns are found to be useful sources for driving these large volume KrF lasers. Presented are some brief background comments on cold-cathode sources. We will also discuss the cathode current emission mechanisms, basic beam transport considerations, pulsed power devices for powering these e guns, and measured e-gun performance. Particular emphasis is given to practical considerations related to the two main LANL KrF/ICF laser systems: the 10-kJ Aurora system and the 100-kJ power amplifier module design.
