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.

A new experimental facility at the University of Wisconsin-Madison, the Dual-Advanced Ion Simultaneous Implantation Experiment (DAISIE), has been designed and constructed to examine tungsten surface damage phenomena. These include microstructure formation and erosion due to helium bombardment as well as the retention of hydrogen gas while under the simultaneous bombardment of helium and deuterium ion beams, as would occur in ITER or other deuterium-burning fusion devices. DAISIE features two ion guns angled at 55° to the sample normal. These guns are independent with respect to beam current, allowing for a high degree of control over the separate D and He beams fluxes and fluences and the composition ratio of these ions impinging upon the tungsten sample surface. Preliminary results are available for helium-only implantations at energies of 30 keV to average fluences of 3 × 1018 He/cm2 in tungsten samples at temperatures of 900°C. As in prior experiments, surface damage appears to be highly-dependent on the crystallography of the individual grains. although a distinct set of helium-induced microstructures from past experiments is observed. Erosion yield is consistent with prior, similar helium irradiation experiments at the University of Wisconsin, but exceeds that predicted by physical sputtering yields and other past sputtering experiments.
