Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

The cryogenic targets of the Laser Megajoule facility (LMJ) are hollow spheres. Their internal walls are covered with a solid layer of frozen deuterium-tritium (D-T). One issue of inertial confinement fusion experiments is to guarantee the quality of the geometry of fuel layer. Cryogenic targets must be cooled at a temperature near the triple point (19K) with a very good stability (0.2mK) for many hours. This period is used to position the target with an accuracy of ±5μm at the center of the experimental vacuum vessel where the 240 laser beams are focalized. A complex cryogenic infrastructure has been conceived to insure the continuity of the cryogenic chain from the filling station located at CEA/Valduc in Burgundy to the LMJ experimental chamber installed in the vicinity of Bordeaux. The design of the target and a detailed description of the infrastructure are presented. A first prototype of cryogenic grip has been fabricated and characterized. Some experimental results are given.
