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.

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.

In the last years, many applications of pulsed laser in precision machining have been demonstrated. Short pulse durations (nanosecond, picosecond and femtosecond) and short wavelength (U.V. and visible) create small heat-affected zones during the interaction with material such as polymers or metals. In the case of excimer lasers, energy carried by ultra-violet photon is sufficient to break apart molecular bonds without thermal effects, particularly in the case of the 3.7 eV C=H bond. All these properties facilitate high spatial resolution and high accuracy processes. This is especially true in the case of high absorbing carbon-hydrogen polymers.An excimer multipulses engraving technique using time-resolved surface ablation was developped using our home-made laser micro-machining work station. This four-axis work station is composed of motor-controlled translation and rotation stages. This experimental set-up was designed to pattern 3D object by the mean of the association of rotative and translative motions. Sinusoidal recording on polystyrene, polyimide and GDP polymers about ten micrometers spatial frequency and a few micrometers amplitude were performed using binary masks with particular shapes.Applications to hydrodynamics modes growth (which have detrimental effect on fusion burn in the "Megajoule laser" LMJ CH-GDP -shell) measurements will be performed on OMEGA laser facility.
