A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

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.
