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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The Laser Megajoule (LMJ) Cryotarget Positioner (PCC) will be used to set cryogenic targets in the vacuum chamber centre of this experimental facility for fusion by inertial confinement. In the French concept, only the targets will be transferred at cryogenic temperature to the PCC, using a Cryotarget Transfer Unit (UTCC). Some of the specifications are very ambitious. Indeed, the targets must be transferred automatically between those cryorobots, at a temperature between 20 K and 29 K. Then, they have to be cooled carefully by the PCC to the triple point (TP) of deuterium-tritium mixture at a rate of 0.5 mK/min. Just below the TP they have to be regulated with an accuracy of +/- 2 mK. Eventually, the DT mixture has to be set 1.5 K below the TP.Scale one prototypes of the cryostats have been built at the Low Temperature Laboratory (SBT) in CEA-Grenoble, France, to deal with specific issues: cryogenic contact resistances, fine cryogenic temperature regulation, test of the feasibility of various thermodynamic paths, 6 degrees of freedom robot positioner, vision control of the transfer and automation. This paper presents the results obtained with these prototypes regarding topics specific to cryogenic transfers, followed by very fine regulation of temperature around 20 K and by dynamic quenching just before the laser shot.
